Spaces outside of parens are implicit ORs here, so all
powerpc+freescale, all arm+freescale and all aarch64.  In the fullness
of time the last one might become all freescale+aarch64.  Bonus points
if we can easily write 'buildman ... ((powerpc|arm|aarch64) & freescale)'

Thinking out loud, the problem is today we have | for OR but we don't
have an AND symbol.  I can do:
$ buildman 'arm|powerpc|aarch64'
Today and get what I want.  But I can't:
$ buildman '(powerpc&freescale)|(arm&freescale)'
