Bugzilla Bug 151587

I set up a cross-compiler from x86_64 to i686 following these instructions: 
http://www.gentoo.org/proj/en/base/embedded/cross-development.xml

Using the xmerge tool listed on that page, texinfo fails to build:

--- 8< ---
(...)
make: Entering directory
`/var/tmp/portage/texinfo-4.8-r2/work/texinfo-4.8/info'rm -f doc.c key.c funs.h

!!! ERROR: sys-apps/texinfo-4.8-r2 failed.
Call stack:

!!! emake doc.c
!!! If you need support, post the topmost build error, and the call stack if
relevant.
--- 8< ---

The makedoc utility exists elsewhere, but after copying it over and trying to
build again the build fails again complaining about missing libraries and such.
 The problem seems to be that texinfo messes up the host/build systems, so it
builds tools that it needs to run on the build system for the host system.

Workaround:  Compile texinfo as if the build system was i686 (ie trick
configure into thinking it's not a cross-compile).  This obviously works on
amd64, but wouldn't work on something that can't run x86 code.
