I've just submitted a CL to clean this up a little so you will need to rebase on
that.

https://codereview.chromium.org/301173002/

After the rebase I think this should look like...

[ 'skia_arch_type == "mips"', {
    'mips_dsp%': 1,
    'mips_dspr2%': 1,
}],

+              'mips_dsp%': 1,
+              'mips_dspr2%': 1,

[djsollen, 2014/05/29 17:01:08]

do you expect all mips builds to support _dsp and dspr2?
