[MIPS32] Fix mono_arch_get_cie_program and ELF_MACHINE undefined issue (#41546)

Hi,

Cross compile for MIPS32:

```
CC=mips-linux-gnu-gcc CFLAGS="-I./libatomic_ops/src" ./autogen.sh --host=mips-linux-gnu --prefix=/home/zhaixiang/mono-mips32-git
make
make install
```

And HelloWorld testcase PASSED:

```
$ ./mono-mips32-git/bin/mono HelloWorld/bin/Debug/netcoreapp3.0/HelloWorld.dll
Hello World!
```

Thanks,
Leslie Zhai
