d63d77a7f0 kconfig/lxdialog: get ncurses CFLAGS with pkg-config
This makes "make menuconfig" also work on systems where ncurses is not
installed in a standard location (such as on NixOS).

This patch changes ccflags() so that it tries pkg-config first, and only
if pkg-config fails does it go back to the fallback/manual checks. This
is the same algorithm that ldflags() already uses.

d35ba8b5ed kconfig/lxdialog: rationalise the include paths where to find {.n}curses{,w}.h
The current code does this:

    if [ -f /usr/include/ncursesw/curses.h ]; then
        echo '-I/usr/include/ncursesw -DCURSES_LOC="<ncursesw/curses.h>"'
    elif [ -f /usr/include/ncurses/ncurses.h ]; then
        echo '-I/usr/include/ncurses -DCURSES_LOC="<ncurses.h>"'
    elif [ -f /usr/include/ncurses/curses.h ]; then
        echo '-I/usr/include/ncurses -DCURSES_LOC="<ncurses/curses.h>"'
    [...]

This is merely inconsistent:
  - adding the full path to the directory in the -I directive,
  - especially since that path is already a sub-path of the system
    include path,
  - and then repeating the sub-path in the #include directive.

Rationalise each include directive:
  - only use the filename in the #include directive,
  - keep the -I directives: they are always searched for before the
    system include path; this ensures the correct header is used.

Using the -I directives and the filename-only in #include is more in
line with how pkg-config behaves, eg.:
    $ pkg-config --cflags ncursesw
    -I/usr/include/ncursesw

This paves the way for using pkg-config for CFLAGS, too, now we use it
to find the libraries.

e62c715b3e menuconfig: optionally use pkg-config to detect ncurses libs
When building ncurses with --with-termlib several symbols get moved from
libncurses.so to libtinfo.so. Thus when linking with libncurses.so, one
additionally needs to link with libtinfo.so.

The ncurses pkg-config module will be used to detect the necessary libs for
linking. If not available the old heuristic for detection of the ncurses libs
will be used.

f755430d79 menuconfig: fix extended colors ncurses support
The ncurses library allows for extended colors. The support for extended
colors support depends on wide-character support. ncurses headers
enable extended colors (NCURSES_EXT_COLORS) only when wide-character
support is enabled (NCURSES_WIDECHAR).

The "make menuconfig" uses wide-character ncursesw library, which can be
compiled with wide-character support, but does not define NCURSES_WIDECHAR
and it's using headers without wide-character (and extended colors) support.

This fixes problems with colors on systems with enabled extended colors
(like PLD Linux). Without this patch "make menuconfig" is hard to use.

8c3f943410 kbuild: Fix gcc -x syntax
The correct syntax for gcc -x is "gcc -x assembler", not
"gcc -xassembler". Even though the latter happens to work, the former
is what is documented in the manual page and thus what gcc wrappers
such as icecream do expect.

This isn't a cosmetic change. The missing space prevents icecream from
recognizing compilation tasks it can't handle, leading to silent kernel
miscompilations.

Besides me, credits go to Michael Matz and Dirk Mueller for
investigating the miscompilation issue and tracking it down to this
incorrect -x parameter syntax.

a0f24a06df kconfig: check ncursesw headers first in check-lxdialog
Commit 8c41e5e363db55d91aa3b1cdce4ab02ad9821de7 added a check for
ncursesw/curses.h for the case where ncurses and ncursesw are build
separately but only one is installed.  But if both are installed,
the headers ncurses/curses.h and ncursesw/curses.h differ, and since
libncursesw will be found first, so should ncursesw/curses.h.

f48bd92285 kconfig: fix menuconfig on debian lenny
In 60f33b8 (kconfig: get rid of stray a.o, support ncursesw, 2006-01-15),
support to link menuconfig with ncursesw library was added.  To compute
the linker command option -l, we check "libncursesw.{so,a,dylib}" to allow
ncursesw to be used as a replacement ncurses.  However, when checking what
header file to include, we do not check /usr/include/ncursesw directory.

Add /usr/include/ncursesw to the list of directories that are checked.
With this patch, on my Debian Lenny box with libncursesw5-dev package but
not libncurses5-dev package, I can say "make menuconfig".

Add a helper script that lists all applets that
- do or may require SUID provileges (busybox.cfg.suid)
- do not require SUID provileges (busybox.cfg.nosuid)

Some setups prefer to build two busybox binaries, one that is suid which
contains all applets that do or may require suid privileges, and a
second one for all the rest (which drops suid). To ease splitting these
two binaries, generate a list of CONFIG_ items for the suid binary.

    kbuild: check if we can link gettext not just compile

    cygwin provides the header file but the lib file needs
    to be added manually. A generic fix is to check if
    we can compile and link a program that uses gettext()
    and if it fails fall back to NO_NLS.

    International users of cygwin may have to specify
    HOST_LOADLIBES := "-lintl" on the make command line.
