[ARM] 3097/1: change library link ordering
Patch from Nicolas Pitre
We have an optimized sha1 routine (arch/arm/lib/sha1.S) meant to
override the generic one in lib/sha1.c.
Unfortunately lib/lib.a is listed _before_ arch/arm/lib/lib.a in the

are not picked up before the generic versions.
This patch is a quick fix to change that ordering for ARM. Here's what

Multicast source filters aren't widely used yet, and that's really the only

only forwarded multicast traffic making use of filters and doing empty-source
