You don't need to separate invocations. "./bjam install" will just work.

./bjam cxxflags=-fPIC install

should work (if you need installing). You can add -n to see the command
lines. You can add -a to rebuild everything -- necessary if you have
already did a complete build without -fPIC.

Note that this flag will only make sense for static builds, since
shared libraries are built with -fPIC anyway.
