Yes, and you can use the same condition used for -Bstatic in
config/darwin.h, so that libgfortran.a is used instead of -Bstatic.
But...

... yes, that's also a nice solution, and it extends well to libgomp.

Yes, the testsuite relies on LD_LIBRARY_PATH and -L, see
gcc/testsuite/lib/gfortran.exp:

    if { $gccpath != "" } {
      if [file exists "${gccpath}/libgfortran/.libs/libgfortran.a"] {
          append flags "-L${gccpath}/libgfortran/.libs "
          append ld_library_path ":${gccpath}/libgfortran/.libs"
      }
      if [file exists "${gccpath}/libgfortran/.libs/libgfortran.${shlib_ext}"] {
          append flags "-L${gccpath}/libgfortran/.libs "
          append ld_library_path ":${gccpath}/libgfortran/.libs"
      }
      if [file exists "${gccpath}/libgfortran/libgforbegin.a"] {
          append flags "-L${gccpath}/libgfortran "
      }
      if [file exists "${gccpath}/libiberty/libiberty.a"] {
          append flags "-L${gccpath}/libiberty "
      }
      append ld_library_path \
        [gcc-set-multilib-library-path $GFORTRAN_UNDER_TEST]
    }

But that's easy to fix in the testsuite.  It's not anymore a one-line
fix, but no more than a dozen lines.
