To be precise: calling make from a make rules is not good if what you
want to do is capture the output.  (Maybe I should fold this into an
autoconf.texi patch..)

That's nice.

Not exactly like this:
|  cd .. && /bin/sh "/tmp/libtool/config"/missing --run automake-1.9a --gnits
| Makefile.am:53: EXTRA_DIST must be set with `=' before using `+='
| Makefile.am:104: EXTRA_DIST multiply defined in condition TRUE ...
| Makefile.am:53: ... `EXTRA_DIST' previously defined here
| make: *** [../Makefile.in] Error 1

Furthermore, fortran tests SKIP now where they used to pass (you missed
one tests/ before fprogram in f77demo-exec.tests).

Other than these nits, seems fine to me.

As reminders:
- make install still misses `libltdl/configure'.
- make uninstall still misses removing libltdl source files.

Yes, but as Bob said, you might want to wait a couple of days before
applying.

Funny thing is, the simplification has not turned into a smaller amount
of Makefile.am code -- the number of non-comment lines even grew.  :)
