Description

Previous literature: #780

The fpm macOS CI does not work anymore even though we've recently updated it (#857) to gcc-10 (gcc-9 was deleted from all github images).

The reason is that gcc-9 dynamic libraries are hardcoded in all published fpm releases from 0.3.0 to the latest 0.7.0
See for example 0.3.0 which is what's currently used:

federico@Federicos-MacBook-Pro Downloads % otool -l fpm-0.3.0-macos-x86_64 | grep dylib
         name /usr/local/opt/gcc@9/lib/gcc/9/libgfortran.5.dylib (offset 24)
         name /usr/lib/libSystem.B.dylib (offset 24)
         name /usr/local/lib/gcc/9/libgcc_s.1.dylib (offset 24)
         name /usr/local/opt/gcc@9/lib/gcc/9/libquadmath.0.dylib (offset 24)

The good news is that the ABI of these libraries is unchanged between gcc-9 and gcc-10. So I think that until a new release is out that's built as a position-independent executable, we can just now create symbolic links to those paths from the new libraries, so the CI keeps working until that time.

Expected Behaviour

CI should work
