Brad King 53e89b6ab0 Add options for separate compile and link sysroots
Add `CMAKE_SYSROOT_COMPILE` and `CMAKE_SYSROOT_LINK` variables to as
operation-specific alternatives to `CMAKE_SYSROOT`.  This will be useful
for Android NDKs that compile and link with different sysroot values
(e.g. `r14` with unified headers).
