Kalev Lember 19febb8bec Bundle mozjs
Bundling mozjs in both gjs and polkit should make it possible to remove
the system wide mozjs78 package from base RHEL 9, which makes it easier
in the future if we need to update gjs to use newer mozjs. At that
point, we can just update gjs to the new mozjs version it needs and not
have to worry about maintaining a system-wide mozjs78 for all of RHEL 9
lifetime.

+dnl
+dnl This macro is intended to be used in those situations when it is
+dnl necessary to mix, e.g. C++ and Fortran 77, source code into a single
+dnl program or shared library.
+dnl
+dnl For example, if object files from a C++ and Fortran 77 compiler must
+dnl be linked together, then the C++ compiler/linker must be used for
+dnl linking (since special C++-ish things need to happen at link time
+dnl like calling global constructors, instantiating templates, enabling
+dnl exception support, etc.).
+dnl
+dnl However, the Fortran 77 intrinsic and run-time libraries must be
+dnl linked in as well, but the C++ compiler/linker doesn't know how to
+dnl add these Fortran 77 libraries. Hence, the macro
+dnl `AC_F77_LIBRARY_LDFLAGS' was created to determine these Fortran 77
+dnl libraries.
+dnl
+dnl This macro was packaged in its current form by Matthew D. Langston
+dnl <langston@SLAC.Stanford.EDU>. However, nearly all of this macro
+dnl came from the `OCTAVE_FLIBS' macro in `octave-2.0.13/aclocal.m4',
