Skip the PR 14918 linker test for ARM targets.
I am applying a patch that has been lying around in the Fedora
binutils sources for a while. It skips the PR14918 linker test for
ARM based targets. This test checks that libgcc is not included in a
link of an empty executable. This works for most targets, but on the
ARM the crt1.o startup code calls __libc_csu_init which is in
/usr/lib/libc_nonshared.a(elf-init.oS). This in turn needs
__aeabi_unwind_cpp_pr0@@GCC_3.5 which is provided by libgcc_s.so.1,
and so the test fails.
