Soft enable runtime cpu detect for armv7-android target, so that it
can be disabled and remove dependency on 'cpufeatures' lib.
Change the arm_cpu_caps implementation selection such that 'no rtcd' takes
precedence over system type.
Switch to use -mtune instead of -mcpu. NDK was complaining about
-mcpu=cortex-a8 conflicting with -march=armv7-a, not sure why.
Add a linker flag to fix some cortex-a8 bug, as suggested by NDK Dev
Guide.
Examples:
Configure for armv7+neon:
./configure --target=armv7-android-gcc \
--sdk-path=/path/to/android/ndk \
--disable-runtime-cpu-detect \
--enable-realtime-only \
--disable-unit-tests
...armv7 w/o neon:
./configure --target=armv7-android-gcc \
--sdk-path=/path/to/android/ndk \
--disable-runtime-cpu-detect \
--enable-realtime-only \
--disable-neon \
--cpu=cortex-a9 \
--disable-unit-tests

Object files are built at the place where configure is launched.

All boolean options can be negated. The default value is the opposite

of that shown above. If the option --disable-foo is listed, then

the default value for foo is enabled.
