 Some comments/questions:
 - in the builds of openssl, libevent, tor, you are setting
 `ANDROID_NDK_HOME` and adding `$ANDROID_NDK_HOME` to `PATH`. Shouldn't
 that be done in `var/setup` in `projects/android-toolchain/config` instead
 of in each project?
 - could you explain (for example in the commit message) why libevent needs
 to be updated from 2.1.8 to 2.1.11?
 - could you explain why the `--disable-libevent-regress` `--disable-
 samples` options are needed to build libevent (and whether it would be
 useful to use them on other platforms too)?
 - in the libevent build, you are adding CC=clang to the configure for all
 platforms. I think it should be added to the android builds only as it
 doesn't seem to be needed for other platforms.
 - it seems we could have a `var/configure_opt` for android in `rbm.conf`
 containing something like `CC=clang --host=[% c("var/host") %] [%
 c("var/configure_opt_project") %]`, where `var/configure_opt_project` is
 defined in each project to define options specific to this project
 - I think the name `var/host` is a little confusing and could be renamed
 to `var/configure_host` to make it more clear where it's used
