commit 6833403fb393a513c77aa3cb8fca7d57b87befe1
Author: Jan (janneke) Nieuwenhuizen <address@hidden>

gnu: autoconf: Support cross-build.
Autoconf cannot be cross-built properly: it lacks the concept of
<tool>-for-build. It runs the host `autom4te' (a perl script) during build.
* gnu/packages/autotools.scm (autoconf)[inputs]: When cross-building, add
perl
and m4.
[native-inputs]: when cross-building, use -for-build names.
[arguments]: When cross-building, add `fake-cross-build' phase to substitute
m4 and perl.
