Maybe the --bionic option should be used here, like it is in build_sdk.py?

There are two things going on here.
  1- We already allow you to pick toolchains using the '-t' command-line option.
  2- We do experimental things with '-x'

Seems to me that -t bionic already covers the --bionic case.  So this '-x' is to
just to add bionic to the experimental switch.

 
   if 'host' in options.toolchain:
     options.toolchain.remove('host')
