Yeah, I've never understood this mania to purge the build process of
any and all use of perl.  If anything, it should *all* be perl so as
to simplify the maint since it's all the same, no matter where you run
perl.

And for those who say "but I need to compile the kernel in my
miniscule, locked down environment" my reply is "cross-compile".

Heck, even pure C code would do the trick here.
