[package] gfortran/10.2: cannot execute ‘f951’: execvp: No such file or directory

[samuel-emrys]

Description

After the changes in #12613, I'm still not able to use the binary gfortran package to compile any code. It fails with:

gfortran: fatal error: cannot execute ‘f951’: execvp: No such file or directory

Relates to #4696

• Operating System+version: Arch Linux
• Compiler+version: Clang 14
• Docker image: N/A
• Conan version: conan 1.53.0

Steps to reproduce

I modified the test package with the following to better use and test the executable produced by the gfortran package:

@samuel-emrys I think your best change is waiting for your PR #13896

[samuel-emrys]

@uilianries agree, I just wanted to capture that the gfortran package is currently broken. Unfortunately #13896 is only a partial solution since it won't build on windows or Macos yet, so I was still hoping for this one to work to enable a lapack recipe
