With mxe-octave

(hg summary:

 native-gcc: remove unintended changes to native-gcc.mk from cs
b1ca68ddd02c)

the cross-build consistently stops at native-gcc with (from the log):

----
I get the same trying to cross compile on my Fedora 20 machine, what OS are
you using?
Attached patch makes it compile for me.
I looks to me that it is trying to pull in some system includes instead of
the mxe build ones, but I couldn't get it to not do that except by compiling
with mpc, mprf etc copied into the gcc build as per the patch.

The other thing needed (on my system as least) has been to copy libgcc.a to
the lib folder when making the dist (Not included in this patch) in order
for gcc to compile programs when installed.
