Hmm, that is a simple, clean idea.
Then, we can simply read out the file

$ cat scripts/min_versions/gcc
4.9.0

I do not know how to handle
per-arch versions in this case.




Or, we might need to stick to shell-scripting
to handle this.

scripts/min_versions/gcc
#!/bin/sh
# SPDX-License-Identifier: GPL-2.0-only
if [ "$SRCARCH" = arm64 ]; then
       echo 5.1.0
else
       echo 4.9.0
fi
