Subject: [PATCH 5/6] common.h: more workarounds for klibc compatibility

Patch is addressing two issues:
* First,  Klibc doesn't have rpmatch().
* Second, Klibc lacks getline()

Fixes:
|   LD      ubi-utils/ubiformat
| .../git/ubi-utils/ubiformat.o: In function `prompt':
| .../git/./include/common.h:157: undefined reference to `getline'
| .../git/./include/common.h:164: undefined reference to `rpmatch'
| .../git/./include/common.h:157: undefined reference to `getline'
| .../git/./include/common.h:164: undefined reference to `rpmatch'

Upstream-Status: Pending
