s390: don't allow CONFIG_COMPAT with LD=ld.lld
When building 'ARCH=s390 defconfig compat.config' with GCC and
LD=ld.lld, there is an error when attempting to link the compat vDSO:
ld.lld: error: unknown emulation: elf_s390
make[4]: *** [arch/s390/kernel/vdso32/Makefile:48: arch/s390/kernel/vdso32/vdso32.so.dbg] Error 1
Much like clang, ld.lld only supports the 64-bit s390 emulation. Add a
dependency on not using LLD to CONFIG_COMPAT to avoid breaking the build
with this toolchain combination.
