Bug#1087502: fiat-ecmwf: FTBFS on arm64: Imported target "MPI::MPI_Fortran" includes non-existent path /usr/lib/x86_64-linux-gnu/fortran/gfortran-mod-15/openmpi

Version: 1.4.0-1
Severity: serious
Justification: FTBFS
Tags: trixie sid ftbfs

Usertags: arm64

During a rebuild of all packages in sid, this package failed to build on
arm64. On amd64 it builds correctly.

It seems that the build uses /usr/lib/x86_64-linux-gnu/ instead of the
arch-specific equivalent, so I suspect the package would fail building
on other non-amd64 architectures as well.

The issue is similar to https://bugs.debian.org/1086834
