Bootstrapping gcc, apparently in stage 3, configuring
libmudflap complains that "gnat" is an unsupported
thread package.
If this is to be expected (and posix or default should be
chosen instead?) then perhaps this is worth a note in
doc/install.texi? Under --enable-threads, it lists
"@item gnat
Ada tasking support."
