This should go in the FAQs because I had to figure this out myself just this week. The toolset.flags rule sets your TOOLSET variable "on" $(targets) for the actions block. The undocumented magic method to retrieve that value in a rule context is the following:
  local toolset = [ on $(targets) return $(TOOLSET) ] ;

rule? I followed an example from the docs which uses the toolset.flags
rule but with no luck.
