Maybe it shouldn't.  Isn't the output of 'glib-genmarshal' target
independent.  I think the best option is to create 'gmarshal.c' on a
native build, and cross-compile that.

So, 

    cd path/to/glib
    mkdir -p build/native build/cross
    cd build/native && do native configure && make
    cd ../cross && do cross configure --disable-rebuilds && make

should do the trick.

I think it is somewhat ugly.  There's should be no need for this
option on a tarball generated with 'make dist'.  If you change
marshal.list, you can easily rebuild a target independent gmarshal.c
with a parallel native build.  On the whole, I don't see this as being
very useful.

I'll leave that up to Owen or Tim.
