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.
