bug#57210: reproducibility: r-bgx tests CPU at configure time

User-agent: mu4e 1.8.7; emacs 28.1

The r-bgx package tests the CPU of the build node to determine whether
to use -march options.

On my laptop it does not, but on berlin it adds -march=k8 to the
compiler options.

This is due to AX_GCC_ARCHFLAG.
