Priorities for release:
[ none ]
+dejagnu support:
+* create site.exp based on known things: tool, srcdir, objdir,
+ maybe host_alias, host_triplet, target_alias, target_triplet,
+ build_triplet (depending on whether AC_CANONICAL_* is used)
+* use RUNTEST_FOR_TARGET in some cases?
+* defining RUNTEST, RUNTESTFLAGS should require dejagnu option
+
should be able to determine what is built by looking at rules (and
configure.in). Then built man pages (eg) could automatically be
omitted from the distribution.
