Passing the `gp relax` flag and sending it to `-shared` shouldn't cause any
problems, since the linker mainly checks whether the `__global_pointer$` symbol
is defined and whether relocation is supported.
So I would incline just pass without checking it's
-shared/-static/-fPIE/&$%^$^, that may just complicate the condition here.
