[tlbuild] xetex not being built

[Karl Berry]

    there I made a mistake in choosing defaults when translating from TL2008 to
    TL2009. Quite easy to fix, but maybe not today.

Sure.

    Which of --with/without-mf-x-toolkit and --enable/disable-ipc should

--with-mf-x-toolkit
--disable-ipc

    Maybe you could add something like TL_MAKE_FLAGS to the Build script, 

Glad that was done.

Thanks,
