Split long lines in configure.in and Makefile.am files

Having very long single lines with lots and lots of things in them
tends to make files hard to diff and hard to merge.  Since our tools
are one-line-at-a-time, we should try to construct lists that way too,
within reason.

This incidentally turned up a few headers in configure.in that we were
for some reason searching for twice.
