Enforce compiling cairo and pixman for WASM with -O3
Earlier, no -O flag at all got used in the cairo and pixman
builds. Which was sad, as these two libraries are performance-critical.
Yes, this change is quick-and-dirty. The proper way would be to modify
things in solenv/gbuild. But that is somewhat complicated.
In general it seems fairly hard to make sure the same compiler flags
get used for every external bundled library. Each external library is
a special snowflake, more or less, with a differently structured
ExternalProject makefile.
For instance for the libwpd library (just picked randomly as an
example), even -O2 gets used. (Which as such is OK.) This despite
solenv/gbuild/platform/EMSCRIPTEN_INTEL_GCC.mk apparently trying to
enforce use of -O1 for Emscripten.
This change has a visible impact on the performance of COWASM.
