Rui Ueyama e6d4154688 [ELF] Generalize tests
With this change, you can now cross compile test cases and run
them on qemu-user. Here is an example to run our test suits in
an emulated ARM32 environment.

$ CC=arm-linux-gnueabihf-gcc \
  CXX=arm-linux-gnueabihf-g++ \
  GCC=arm-linux-gnueabihf-gcc \
  GXX=arm-linux-gnueabihf-g++ \
  OBJDUMP=arm-linux-gnueabihf-objdump \
  MACHINE=arm \
  QEMU='qemu-arm -L /usr/arm-linux-gnueabihf' \
  make -j16 test
