I have to apply the following patch on your patch in order to be able to
compile it.  ("MULTIBUILDTOP" is empty here and the library is not in
"/libbacktrace".)

Additionally, I wonder whether one should have:

--- a/Makefile.def
+++ b/Makefile.def
 languages = { language=fortran;        gcc-check-target=check-fortran;
                                lib-check-target=check-target-libquadmath;
+                               lib-check-target=check-target-libbacktrace;
                                lib-check-target=check-target-libgfortran; };
 languages = { language=java;   gcc-check-target=check-java;




And in the same file, I wonder which of the following two is correct:

+dependencies = { module=all-target-libgfortran; on=all-target-libbacktrace; };

or

+dependencies = { module=configure-target-libgfortran;
on=all-target-libbacktrace; };
