Unfortunately, that does not help.

When running the testsuite in the build directory (cd $BUILD/gcc),
I get:

testsuite/gfortran.dg/pr93524.c:5:10: fatal error: ISO_Fortran_binding.h: No such file or directory

I wonder whether we need to do the same as with libgomp and libstdc++,
namely adding a libgfortran/testsuite/ to handle this.

In any case, compiling with '-v' shows all currently
searched include paths are the same for -m32 and -m64,
which is will pick up the wrong one for -m32. I tried it
by using the command line used when running in tree
   make check-fortran RUNTESTFLAGS="dg.exp=pr93524.f90 --target_board=unix\{-m32,\}"
