arm_neon.h is safe to use without flags when just the file itself is
self-contained with GCC target pragmas.

configure gets 2 new options:
--enable-neon / --enable-neon-rtcd
the NEON modules are split to their own convenience lib and built with
auto-detected flags if none are given via CFLAGS.
the /proc/cpuinfo check will only be used for armv7 targets whose
toolchain does not enable NEON by default or didn't have NEON forced by
the CFLAGS from the environment.

TEST_AND_ADD_CFLAGS tests flags independently from AM_CFLAGS. The lack
of -Wformat may cause -Wformat-* checks to fail (gcc 4.9), though in the
end they would have succeeded with -Wall present.
