Modifications to enable OpenMP in Android.
This patch enables OpenMP support in the Android NDK by modifying the following:
Specify that pthreads are supported in -lc instead of -lpthread (linux-android.h)
Change the order of ANDROID_LIB_SPEC and LINUX_TARGET_LIB_SPEC so the above change will take precedence (linux-eabi.h)
Modified autoconf for libgomp to check to see if the pthread libraries exist in libc (configure.ac)
Added include to env.c so PAGE_SIZE is defined.
To enable these changes, add "--enable-libgomp" to configure command under build-gcc.sh.
