Comment (by boklm):

 An other option is using a separate `step` in `projects/geckoview/config`
 to merge the .aar files. In `projects/geckoview/config` we would add
 something like this:
 {{{
 steps:
   merge_aars:
     merge_aars: |
       #!/bin/bash
       # commands to merge .aar files

     input_files:
       - name: geckoview_armv7
         project: geckoview
         pkg_type: build
         target_prepend: torbrowser-android-armv7
       - name: geckoview_aarch64
         project: geckoview
         pkg_type: build
         target_prepend: torbrowser-android-aarch64
 }}}

 And in `projects/fenix/config` we would have something like this:
 {{{
 input_files:
  - name: geckoview
    project: geckoview
    pkg_type: merge_aars
 }}}

 In `rbm.conf` we also need to set
 `var/container/disable_network/merge_aars` to prevent network access
 during the `merge_aars` step.

 Then we can use the following command to build geckoview for a single
 arch:
 {{{
 ./rbm/rbm build geckoview --target nightly --target torbrowser-android-
 x86_64
 }}}
 Or this command to build it for all archs and merge them:
 {{{
 ./rbm/rbm build geckoview --step merge_aars --target nightly --target
 torbrowser-android-all
 }}}
