Comment (by gk):

 Okay, for the fat .aar creation we would have to do in the `steps` step:

 1) Specify the archs we support like so:
   `export MOZ_ANDROID_FAT_AAR_ARCHITECTURES=armeabi-
 v7a,arm64-v8a,x86,x86_64`
 2) export the relative paths to the respective arch dependent .aar file
 using
   `MOZ_ANDROID_FAR_AAR_ARMEAVI_V7A`, `MOZ_ANDROID_FAT_AAR_ARM64_V8A`,
 `MOZ_ANDROID_FAT_AAR_X86`, and `MOZ_ANDROID_AAR_X86_64`
   The full path is assembled out of `MOZ_FETCHES_DIR` + the relative ones
 above (so we need to export the absolute `MOZ_FETCHES_DIR`, too.
 3) We should be able to run now `./mach build android-fat-aar-artifact`
 and the .aar should be in `$DIST/fat-aar`

 (I've not tested that locally, yet, though)
