kbuild: fix CONFIG_CC_CAN_LINK(_STATIC) for cross-compilation with Clang
scripts/cc-can-link.sh tests if the compiler can link userspace
programs.
When $(CC) is GCC, it is checked against the target architecture
because the toolchain prefix is specified as a part of $(CC).
When $(CC) is Clang, it is checked against the host architecture
because --target option is missing.
Pass $(CLANG_FLAGS) to scripts/cc-can-link.sh to evaluate the link
capability for the target architecture.
