Re: texinfo not cross compiling

[Karl Berry]

    I have tried various ways on my system which is a derivative of CLFS
    and the ROCK linux project.

The only thing that is special about Texinfo and cross-compiling is the
need to build some of the tools with the native compiler.  Below is what
we have in configure.ac.  I've never attempted cross-compilation myself,
so don't have any good advice.  Sorry.

# We need to run some of our own binaries, most notably makedoc, but as
# long as we have this process, we also use our own makeinfo and
# install-info.
#
# This means that if we are cross compiling, we have to configure the
# package twice: once with the native compiler (this is done in a
# subdirectory $native_tools), and once with the cross compiler.
# The former is invoked automatically here, with --host=$build.
# $native_tools is also added to SUBDIRS in the main Makefile.am,
# so that make compiles the native tools first.
