commit a735e99b56ecaf6d6bd8e6af59e27eb7720906f2

Add support for building chromium on mips64el using GN.

Currently, GN supports 32-bits LittleEndian targets (mipsel),
but GN does not supports 64-bits mips64el(such as loongson3a platform).

In order to successfully compile chromium on the mips64el platform,
this provides support for 64-bits LittleEndian targets with GN.
