Multi-target build #8156
Description
Describe the problem you are trying to solve
When building rust code for an Android app, it is common to build for multiple targets, e.g. (ARM, x86) ⊗ (32 bits, 64 bits). While cargo build is already parallel in some sense, LTO (or last step compilation in general) is single threaded and can take a long time to run. It makes sense to use up the CPU resources for building other targets.
Describe the solution you'd like
Multi-target build with --target=armv7-linux-androideabi --target=aarch64-linux-android ....

Thanks for the report! This is actually a refactoring I've wanted to do for some time now, so I've mustered up the motivation and pushed up #8167 to implement this.
