Subject: [PATCH] configure.ac: fix bashism in ARM optimization handling

Submitted upstream:

http://lists.xiph.org/pipermail/opus/2013-December/002422.html

Breaks configure when /bin/sh isn't bash with:

configure: Trying to force-enable ARMv6 media instructions...

checking if assembler supports ARMv6 media instructions on ARM... yes

configure: Trying to force-enable NEON instructions...

checking if assembler supports NEON instructions on ARM... yes

./configure.lineno: 12799: Bad substitution

Fix it by using the %% expansion to remove everything from the first

space instead.
