Specifying the architecture directly works.
I used the following snippet
cc -march=native -Q --help=target
to query which architecture native would give me then replaced it. Both
windows (nehalem) and linux (tigerlake) seem to work fine so far, but
the packages that failed to compile previously need to be reinstalled I
guess.
Thanks for the help
