AC_SUBST: document and test previous patch
Test that: invalid variable names are detected, that the variable
name does not get macro expanded, that assignment to the variable
works whether as part of AC_SUBST or independently, that the last
assignment wins.
* doc/autoconf.texi (Setting Output Variables) <AC_SUBST>: Mention
that variable does not overlap with macros.
* tests/base.at (AC_SUBST): New test.
