You misunderstood. The "top level targets" are the ones you regularly deal
with, the targets that you define in the Jamfile: exe, lib, dll... There are
other targets generated internally, for example all the source files, and
the generated *.obj or *.o files. When I said you can specify it on a top
level target basis I meant this, for example:

exe test : a.cpp b.cpp : <instruction-set>ultrasparc : debug ;

But because a.cpp and b.cpp are not top level targets you can't tell BB to
compile a.cpp with one instruction set and b.cpp with another.

In the tools file you add something like what the gcc-tools.jam does:

flags snps HDRS <instruction-set>ee : $(SCE)\\EE\\INCLUDE ;
flags snps HDRS <instruction-set>iop : $(SCE)\\IOP\\INCLUDE ;

AND, you modify features.jam to add "ee" and "iop" as valid values for the
instruction-set feature.
