New submission from Ismail Donmez <ism...@namtrac.org>:
The check under Modules/_ctypes/libffi/configure.ac does;
echo '.text; foo: nop; .data; .long foo-.; .text' > conftest.s
if $CC $CFLAGS -c conftest.s 2>&1 | grep -i warning > /dev/null; then
libffi_cv_as_x86_pcrel=no
fi
With clang; we get:
clang: warning: argument unused during compilation: '-g'
So it fails to detect pc relocation support due to an unrelated warning.
