Remember that this toplevel configure is shared between gcc, binutils, gdb,
newlib, insight, and cygwin. It should not list gcc-specific options; the fact
that it does now is just an artifact resulting from how those options happen to
be implemented. It would make no sense for e.g. the next gdb release to
contain documentation for a --disable-libmudflap option in its --help.
In an ideal world the toplevel configure would check at runtime and see what
subdirs are present and adjust its output accordingly. Also --help=recursive
should be fixed, as there are tons and tons of options that are only shown if
you run configure --help in the subdirs, but are never shown by the toplevel
--help.
