kbuild: drop support for cc-ldoption
If you want to see if your linker supports a certain flag, then ask the linker directly with ld-option (not the compiler with cc-ldoption). Checking for linker flag support is an antipattern that complicates the usage of various linkers other than bfd via -fuse-ld={bfd|gold|lld}.
