Bug#451136: devmapper: mass bug filing for cross-build support

[Neil Williams]

Package: devmapper
Version: 2:1.02.20-2
Severity: wishlist
Tags: patch

In line with the other cross-building support bugs:
http://lists.debian.org/debian-devel/2007/11/msg00116.html

This patch is necessary to allow devmapper to cross-build in Debian.
(The cache file is handled internally by Emdebian until such time as
another method can be devised but the use of the --cache-file option
will remain.)

This occurs because the cross building tools have been rewritten to
support CC_FOR_BUILD for packages that compile internal build tools 
and therefore the tools no longer explicitly override the MAKEFLAGS.

Thanks.
