[Buildroot] [PATCH] heirloom-mailx: run makeconfig in configure step

[Arnout Vandecappelle (Essensium/Mind)]

The heirloom-mailx Makefile runs makeconfig if this has not been done
before.  In a parallel build, this means makeconfig may be run several
times in parallel because there are two targets that depend on makeconfig.
See for instance
http://autobuild.buildroot.net/results/d24854be69961f71db189f9d804d4bd2cfa078da

To avoid this, run makeconfig in the configure step, which is not parallel.

I couldn't actually reproduce the build failure, but the build log gives
a good indication that this is what went wrong.
