77e2bde6a5 trylink: include LDFLAGS when checking linkage
The user might be including options in their LDFLAGS (like -fuse-ld=gold)
that change the behavior of the linker and thus change the results of the
flag tests.  Make sure we include the user's LDFLAGS when running these
tests so we filter out flags that will fail when used later on.

58d0e20ad0 scripts/trylink: remove $CPPFLAGS
We don't use it in final link, should not use it in check_FOO then.
This uncovered a logic bug in glibc check...

To that end, *make it complain* when check_cc fails on options

The CPPFLAGS/CFLAGS settings might have features that matter, so make
sure we utilize them when testing the compiler.

3eab2b7675 trylink: only prefix libs with -l
If our pkg-config queries pass back a flag like -pthread, the trylink
script will expand that to -l-pthread.  So change trylink to only add
the -l prefix to a value that doesn't have a - prefix already.

8d91c13df5 - fix bug where we linked again -lm even though it is not needed.
For BBOX_LIB_LIST="crypt m" trylink ... with just applet true, we pulled in
  libm because in this case we tried to use invalid flags (plain "-l" without
  a lib) which of course failed, thus the script thought that -lm was needed.

  The fix is not to pass "-l" without a lib if we are about to check if any
  or the last remaining lib is really needed.
