Not totally sure I understand your questions.. But here's a possible 
answer. It prevents builds with anything but gcc for my_variant.

rule only-gcc ( toolset variant : subvariant-path properties * )
{
local no-build = <build>no ;
if [ MATCH .*(gcc).* : $(toolset) ]
{
no-build = ;
}
return $(subvariant-path) [ impose-requirements $(properties) : 
$(no-build) ] ;
}

variant my_variant : : only-gcc ;

This is untested, so syntax, and actual operation may vary from my 
assertions ;-)
