POWER10: Fix ld version detection 

LDVERSIONGTEQ35 needs to escape the '>' character.

LDVERSIONGTEQ35 is checking the system ld version which may be different
to the toolchain being used to compile OpenBLAS. We don't have a path
to the linker in our Makefiles, so (ab)use gcc -Wl,--version to get the
version of ld in our toolchain.
