For target:

exe a : a.cpp : <cflags>-march=pentium3 <cflags>-fomit-frame-pointer ;

I've just added docs on this to

http://boost.org/boost-build2/doc/html/bbv2/advanced/builtins/features.html

For project: using project requirements

http://boost.org/boost-build2/doc/html/bbv2/advanced/jamfiles.html#bbv2.advanced.projects

V2 does not generate any of those options itself, so you're safe.
