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

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

[Baruch Siach]

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.
