The problem is that the the toolset name doesn't reliably convey
the needed information.  Specifically, there are tests which are pointless
to run if the platform doesn't handle wide character i/o.  Some
versions of gcc implement it - others don't.  And I can't figure
out how to know with certainty in all cases.

What I'm thinking about is more along the lines of the following:

There would be a test as part of "config" group which results
passes if wide char i/o is supported on the platform.  Then,
using "dependency" facilty - new in v2 I believe, condition
the tests which require wide char i/o on the successful passing
of the wide char i/o test.  I'm not sure if v2 can be setup for
this but this is what I would like to do.

In fact, I would like to extend the concept even further.  There
isn't much point in running serialization tests on say - variant, if
the other more basic tests for variant aren't all passing.  So
I would think it valuable to condition these tests also.

All this required investigation and experiment - certainly
not something appropriate for a "release" branch.

Not as much as I should.  But in this particular case, some information
can be found in the serialization documentation:
