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

[Thomas Meyer <thomas@m3y3r.de>]

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
  CHK     include/generated/uapi/linux/version.h
  HOSTCC  scripts/basic/fixdep
  HOSTCC  scripts/basic/bin2c
  HOSTCC  scripts/unifdef
  CC      arch/x86/um/user-offsets.s
  CHK     include/generated/user_constants.h
  CHK     include/config/kernel.release
  CHK     include/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
