Build system assumes lfortran broken because of -m32 flag (?) #693
Description
Description
I was writing a portfile for stdlib anew, since being on a different machine, and did not specify gfortran; CMake build script opportunistically picked lfortran (which is fine after all), but decided it is broken because of unexpected flags :)

Expected Behaviour
Perhaps build system should be aware of 32-bit platforms.
