Subject: [PATCH] include/common.h: fix build against current uClibc

Commit dbe0fd17f2 (mtd-utils: new prompt() helper for talking to the user)

introduced a rpmatch() call. However, uClibc versions older than (not yet

released) 0.9.34 don't have rpmatch() implementation. Add one.

Patch status: sent upstream, http://patchwork.ozlabs.org/patch/338748/
