This is really a function of the assembler, not the compiler.

When using ELF, the assembler should always generate a relocation if
the function is not static.  If the function is static, I don't think
there is any way to force the relocation.  You would have to add an
option to the assembler.  If you are using gas, you would want to
change adjust_reloc_syms in gas/write.c.
