Or put the version of the compiler that works in the source tree
with the kernel and then build it as part of the full build.

It is enough of a PITA having to find libelf-devel in order to
build objtool, never mind having to find the correct version
of something else.

gcc tends to be available and the version doesn't matter too much.
But ever that gives problems.
