I wrote the initial version of the autoreconf support in this script,
originally it only had gdb, gdbserver and gdbsupport.  But Christophe
later added all the directories that currently work with a simple
autoreconf.  At this point, I think it would make sense to flip the
logic and list only the directories that don't work with a simple
autoreconf, and then work on reducing that list to 0.
