Commit 61f60bac8c ("gcc-plugins: Change all version strings match
kernel") broke parallel builds.
Instead of adding the dependency between GCC plugins and utsrelease.h,
let's use KERNELVERSION, which does not require any build artifact.
Another reason why I want to avoid utsrelease.h is because it depends
on CONFIG_LOCALVERSION(_AUTO) and localversion* files.
(include/generated/utsrelease.h depends on include/config/kernel.release,
which is generated by scripts/setlocalversion)
I want to keep host tools independent of the kernel configuration.
There is no good reason to rebuild GCC plugins just because of
CONFIG_LOCALVERSION being changed.
We just want to associate the plugin versions with the kernel source
version. KERNELVERSION should be enough for our purpose.
