ffmpeg | branch: master | Mans Rullgard <mans at mansr.com> | Mon Dec  3 21:47:17 2012 +0000| [f0fe245bc31cf4fa3b3ed0240cd1ab6f0d5043ea] | committer: Mans Rullgard

configure: arm: set fast_clz and fast_unaligned in cpuflags section

These are properties of the targeted core and do not depend on
specific assembly support in the toolchain which if missing will
render the controlling options here disabled.
