LOG: [flang] Use clang sysroot image to test fastmath linking

This test has been very unreliable across different machines. Update it
to use clang's sysroot image so that the fastmath object file name is
stable across different distributions and distro types.

Based on clang/test/Driver/linux-ld.c
