Fix the Android/MIPS build.

This patch fixes the build for Android on MIPS when
using the latest official Android NDK (r9):

- Update src/common/android/include/elf.h to add a missing
  definition for SHT_MIPS_DWARF.

- Add src/common/android/include/sgidefs.h required by LSS
  when compiling for MIPS.

- Update android/run-checks.sh to work properly with
  the --abi=mips option. All tests were passed succesfully
  with an emulator system image running Android 4.2.

- Update other Android-specific files.
