This syncs us with binutils/gdb's toplevel configure as of
987db70acefd0b223a8df2240d4e5ca544cc0a91.

There's not much notable here, just gprofng (which is in binutils) being
disabled for musl and a new target which got added on that side too.

The only part which may look interesting is the baseargs->bbaseargs
change which goes back to Arsen's gettext work and a fixup which
landed for that on the binutils side in
9c0aa4c53104b1c4333d55aeaf11b41053307929.

	* configure: Regenerate.
	* configure.ac: Sync with Binutils.
