redhat/configs/process_configs.sh: Fix race with tools generation
Kernel builds are occasionally failing with (for example):
Processing /home/prarit/rpmbuild/BUILD/kernel-5.17/linux-5.17.0-0.test.fc35.x86_64/configs/kernel-5.17.0-s390x.config ...

make[1]: *** Deleting file 'scripts/basic/fixdep'
make: *** [Makefile:559: scripts_basic] Error 2
This occurs because the makes are conflicting with one another to create
the same files. This can be fixed by having the first make run on it's
own, and then having the remainder run in parallel.
