It should cover most purposes of running gdb from the build directory, since I don't see much reason to change --bindir, --exec-prefix, and/or --with-gdb-datadir if gdb won't be installed, unless for testing those flags, in which case gdb will likely have to be installed anyways.

It's still having "make all" install something outside of gdb's build dir.

I won't object if someone else approves, but I'll be happy to remove
it if it ever bitrots or becomes problematic. :-)
