Hi,
Sorry for criticism, but the patch is not complete.
CONFIG_X86 deals with target architecture, at the same time the problem
deals with the host architecture.
Imagine, that I run arm, aarch64 or something else and do
cross-compiling kernel for x86 on it. Then CONFIG_X86 will evaluate to
'y' and make will try to compile the apps with the host-compiler, which
is not x86 one.
