Gaby,

Here are some simple patches to build-improvements required by
some versions of awk. Of course you need also to rebuild the
corresponding Makefile.in files.

-----

address@hidden:~/axiom.build-improvements$ hg diff .

The following patch ensures that if make is restarted, it does
not append extra rules to more-rules.mk.

There was a minor typo in the else clause: should be tab instead
of spaces. Plus we should not escape the $ in awk since newer
versions of awk (> 3.79) treat this as a literal.
