That's not currently expected to work.  I've not been able to get gcc to
build for any native build setup.  So you need to try with USE_SYSTEM_GCC
set to yes.

Longer term, yes, in some cases it would be nice to be able to build GCC
from sources.  For example, if the system version of GCC won't work for
building Octave or if we want better control over the build environment. 
  But otherwise, using the copy of GCC already installed should usually be
OK.

On a side note, I could compile binutils, and gcc 4.8.1 without any issues
outside of mxe - I didn't try bumping the rev of gcc I mxe and seeing it
worked or not, or whether 4.7 worked outside of the mxe scripts.
