x86: add a Kconfig symbol for when relocations are needed
We only need to build relocations when we are building a 32-bit relocatable kernel. Rather than unnecessarily complicating the Makefiles, make an explicit Kbuild symbol for this. [ Impact: permits future cleanup ] Signed-off-by: H. Peter Anvin <hpa@zytor.com> Cc: Sam Ravnborg <sam@ravnborg.org>
