    (''' MOZ_ENABLE_SKIA_GPU ''', r'''  '''),
    (''' MOZ_ENABLE_SKIA ''', r'''  '''),

This is the issue: MOZ_ENABLE_SKIA_GPU is off (correct, does not work on
any big endian platform so far). But MOZ_ENABLE_SKIA should be on.

With both off, the gfx/skia exports are not generated, so the headers later
are not found.
