Build freetype with -Wno-misleading-indentation

[sbc100]

This is new compiler warning in clang that was causing the build
to fail.

lgtm if this works, but I don't think emcc_args are sent to every library building command? We don't invoke emcc ourselves there, the config/make system does.

I'd guess we need to add this in the freetype configure, or add CFLAGS to it's configure command, something like that.

(But, maybe we did forward emcc_args to there and I forgot?)

These flags are sent to the library build (via CFLAGS I guess). this is why we include the emcc_flags in the name of the cached library, since we build a different version for each flag combination.

This is why its failing, because we include -Werror by default in the tests.
