Original issue's description:
> MIPS: Fix mksnapshot on big-endian.
>
> Paritally revert standalone.gypi changes in a451bd1a and introduce a new separate variable for the mkpeephole.
>
> On big-endian MIPS, qemu is used to build the snapshot,
> because there's no simulator support for big-endian MIPS.
