[PATCH] um: Don't build arch/x86/um/user-offsets.s with gcc plugins

[Thomas Meyer]

For some reasons I don't know users-offsets.s get's build before the
gcc-plugins itself.
This patch fixes the problem by not using the gcc-plugins for building
user-offsets.s

make order example:
$ make ARCH=um
 CHKÂÂÂÂÂinclude/generated/uapi/linux/version.h
 HOSTCCÂÂscripts/basic/fixdep
 HOSTCCÂÂscripts/basic/bin2c
 HOSTCCÂÂscripts/unifdef
 CCÂÂÂÂÂÂarch/x86/um/user-offsets.s
 CHKÂÂÂÂÂinclude/generated/user_constants.h
 CHKÂÂÂÂÂinclude/config/kernel.release
 CHKÂÂÂÂÂinclude/generated/utsrelease.h
 HOSTCXX -fPIC scripts/gcc-plugins/latent_entropy_plugin.o
 HOSTLLD -shared scripts/gcc-plugins/latent_entropy_plugin.so
 HOSTCXX -fPIC scripts/gcc-plugins/structleak_plugin.o
 HOSTLLD -shared scripts/gcc-plugins/structleak_plugin.so
