Unfortunately, immintrin.h (which is also included by SkTypes)
includes xmmintrin.h which includes mm_malloc.h which includes
stdlib.h for malloc even though, from the implementation, it is
difficult to see why.
Fortunately, arm_neon.h does not seem to be involved in such
shenanigans, so building for Android will keep things sane.

Motivation: PDF/A metadata will need the creation date embedded in it.
Also, GetDateTime returns local time in Win32. This now behaves the
same as on Unix systems.
