#### Differences between Android.mk and Android.bp
* Android.mk files often have multiple modules with the same name (for example
for static and shared version of a library, or for host and device versions).
Android.bp files require unique names for every module, but a single module can
be built in multiple variants, for example by adding `host_supported: true`.
The androidmk converter will produce multiple conflicting modules, which must
be resolved by hand to a single module with any differences inside
`target: { android: { }, host: { } }` blocks.
