[FFmpeg-devel] [PATCH] configure: Remove dcbzl check for e500v1 and e500v2 architectures

[Peter Krefting <peter@softwolves.pp.se>]

The DCBZL instruction is not available for the e500v1 and e500v2
architectures, but may still be recognized by the toolchain, so we need to
remove the test for it explicitly for these architectures.

This was originally fixed by commit d5733936d857ce5c7d28c0bc9e89a2e2548f8895
in version 2.2, but later broke in a merge which introduced a "disable dcbzl",
forgot to check for it in the ppc branch.
