+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.
