Valid linker options should be treated for elf consistently
with the linux-gnu target.
I'm not sure about the undocumented -h option (blindly copied
LINUX_TARGET_LINK_SPEC from aarch64-linux without the
dynamic-linker flag).
(Not passing -shared can cause broken vdso.so in the linux
kernel when it is built with the elf toolchain.)
