This is what we did in our boost 1.36 RPM spec file. Probably not
the best way to do this, but it worked:

%build
./configure --prefix=%{_prefix} --libdir=%{_libdir}
cat Makefile | sed -e 's/BJAM_CONFIG=/BJAM_CONFIG=--layout=system 
--build-type=complete cxxflags=-fPIC/' > Makefile.new
mv Makefile.new Makefile
make all
