Commit 4efca4ed ("kbuild: modversions for EXPORT_SYMBOL() for asm") adds
modversion support for symbols exported from asm files. Architectures
must include C-style declarations for those symbols in asm/asm-prototypes.h
in order for them to be versioned.
Add these declarations for x86, and an architecture-independent file that
can be used for common symbols.
User impact: kernels may fail to load modules at all when
CONFIG_MODVERSIONS=y.

This is an unsplit version (x86/include/ and include/ together).
