Support OpenMP+Bionic on ICS/GCC-4.7.2 for task parallelism
The patch supports OpenMP library to parallelize the existing
C/C++ code (e.g: for task parallelism) rapidly/easily without
any modification of android platform on multicore embedded devices.
The original patch is made by Keith Obenschain (using GCC 4.4.3).

I just moved GCC version from 4.4.3 to 4.7.2 for ktoolchain
version 2.5. The patch is good to me when I evaluate a lot of
C/C++ source code with OpenMP's #parama. we move the version
of OpenMP from version 2.5 to version 3.1.
Please, refer to the "kandroid toolchain" menu in www.kandroid.org
to compile source code including bionic and openmp library on real
Android devices.

I tested Openmp library with the latest GCC 4.7.2 on Android/ARM
devices as following. Please refer to the below example.
geunsik@rhel6$> ./arm-linux-androideabi-gcc openmptest.c -L
/usr/local/ktoolchain-cortexa9-ver2.5-20120515-bionic/arm-linux-androideabi/lib
-lgomp -o openmptest [ENTER]
