elfcore: fix building with clang
kernel/elfcore.c only contains weak symbols, which triggers a bug with
clang in combination with recordmcount:
Cannot find symbol for section 2: .text.
kernel/elfcore.o: failed
Move the empty stubs into linux/elfcore.h as inline functions. As only
two architectures use these, just use the architecture specific Kconfig
symbols to key off the declaration.
