Subject: [PATCH] maint: allow selecting compiler for ManyConfigTests

Instead of hardcoding the compiler as `cc`, let a CC environment
variable dictate which compiler to use.

For example, in macOS/arm64 where the GNU compiler is provided by
brew the following will allow using it instead of the system compiler
(which ALSO answers to `gcc` eventhough is `clang`)
