Fix -nopie/-nopie check.
...
We don't use lgcc_s but missing lgcc_s or another library cause test to fail.
So use -nostdlib.
We need to use -Werror to avoid warning-generated case to be accepted.
Clang uses -nopie rather than -no-pie. Check both and use whichever one works.
Additionally android clang passes -pie to the linker even though it doesn't
define __PIE__. So if compilation without no-pie logic fails add -nopie/-no-pie
even if __PIE__ is not defined.

Check that compiler supports -no-pie and add it to linker flags.

That's what Makefile will use and it is required if unusual flags
must be passed to linker (e.g. to build ppc32 code on ppc64le with clang).

fix removal of {cpu,machine} links on mingw/msys
...
At least on Windows 2003 using "ln -s dir1 dir2" in msys shell succeeds,
but results in what looks like hard link. Subsequent "rm -f dir2" (e.g.
during second config.status invocation) fails. Check that we also can
remove link to directory.
Make it more clear in message that we are checking "ln -s".
