configure.ac: fix bashism in ARM optimization handling

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.
