Various tools are Linuxish and should thus only attempted to build on
Linux only. Some features are also Linux-only.
Also, libresolv is used on all GNU platforms, notably GNU/Hurd and
GNU/kfreeBSD.

Running an applet with '--help' as its only argument is treated
as a special case. If additional arguments follow '--help' the
behaviour is inconsistent:
- applets which call single_argv() print help and do nothing else;
- applets which call getopt() report "unrecognized option '--help'"
and print help anyway;
- expr says "expr: syntax error" and doesn't print help;
- printenv silently ignores '--help', prints any other variables
and doesn't print help;
- realpath says "--help: No such file or directory", prints the path
of any other files and doesn't print help.
If the first argument is '--help' ignore any other arguments and print
help. This is more consistent and most likely what the user wanted.
See also commit 6bdfbc4cb (libbb: fix '--help' handling in
FEATURE_SH_NOFORK=y).

Patch by soeren@soeren-tempel.net
The idx variable points to a value in the stack string (as managed
by STPUTC). STPUTC may resize this stack string via realloc(3). If
this happens, the idx pointer needs to be updated. Otherwise,
dereferencing idx may result in a use-after free.

The line editing code and ash disagree when the current directory
is changed to a symbolic link:
~ $ mkdir real
~ $ ln -s real link
~ $ cd link
~/real $ pwd
/home/rmyf36/link
Note the prompt says we're in ~/real. Bash does:
[rmy@random ~]$ cd link
[rmy@random link]$ pwd
/home/rmyf36/link
Ash uses the name supplied by the user while the line editing code
calls getcwd(3). The discrepancy can be avoided by fetching the
value of PWD from ash.
Hush calls getcwd(3) when the directory is changed
so there's no disagreement with the line editing code.
There is no standard how shells should handle cd'ing into
symlinks.
