Problem: Android helpers should export more compilation chain related variables

Browse Source 
Among them, CC, LD, CFLAGS, ... could be useful for other tools.

Reason: Many are calculated as "local" to a particular function, which makes
them unavailable outside this helper function.

Solution: Export more variables (CC, LD, CFLAGS, ...).

New exported variables are prefixed with ANDROID_BUILD_xxx.
This naming is expected to avoid any conflicts/problem with other tools:
- ANDROID_BUILD_CC
- ANDROID_BUILD_LD
- ANDROID_BUILD_CFLAGS
- ...
