Building asm-offsets.h has been moved to a seperate Kbuild file located in the top-level directory. This allow us to share the functionality across the architectures. The old rules in architecture specific Makefiles will die in subsequent patches. Furhtermore the usual kbuild dependency tracking is now used when deciding to rebuild asm-offsets.s. So we no longer risk to fail a rebuild caused by asm-offsets.c dependencies being touched. With this common rule-set we now force the same name across all architectures. Following patches will fix the rest. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
