[HarfBuzz] Build-related questions

[Vincent Isambart]

Hi,  

2 questions/remarks after trying to build HarfBuzz for iPhone:
- The build process adds the -mstructure-size-boundary=8 flag when building on ARM, but clang doesn’t support it. Couldn’t that flag added on ARM only when the compiler is GCC?
- use of UCDN is disabled when building HarfBuzz with glib support, but why is it not when building HarfBuzz with ICU support?

Thanks,
Vincent
