croot make c2hal -j64
c2hal [-g] [-o dir] -p package (-r interface-root)+ (header-filepath)+
-o output path: If missing, the second half of a relevant interface-root will be used.
-p package: For example android.hardware.baz@1.0. This will be used as the package in .hal files and will also be used to construct the correct directory structure.
-g: Enabling this flag changes the behavior of c2hal to parse opengl files.
-r package:path root: For example 'android.hardware:hardware/interfaces'.
