Android 4.2 CTS release 2
Added missing defines and headers

Added more defines and headers to make this prebuilt capable of compiling
all host binaries in Android.

1. Added more defines in sysroot/usr/include/asm/unistd_32.h, from
   linux-libc-dev_2.6.32-21.32_i386.deb (lucid)
2. Added more magic numbers in sysroot/usr/include/linux/magic.h,
   also from linux-libc-dev_2.6.32-21.32_i386.deb (lucid)
3. Added new sub-dir sysroot/usr/include/sound, from
   linux-headers-2.6.24-16_2.6.24-16.30_all.deb (hardy)

build-hardy-toolchain.sh will be enhanced later to automate this
