Subject: [PATCH 260/261] Make module directory specifiable on the configure
 command line.

Currently ppc, ppc64, and ppc64le all wind up with modules in
/usr/lib/grub/powerpc-ieee1275, because powerpc is the target cpu in
grub's eyes.  This causes file conflicts between "noarch" module
packages.

This patch allows --with-moduledir=%{arch} to be specified on the
configure command line to override the directory name for a specific
build, to disambiguate the various ppc directories.

Resolves: rhbz#1455243
