Look at one of the many targets that already does things this way. 
xstormy16 is a relatively recent embedded port, and seems to do it the 
"right" way.  See the xstormy16 support in libgloss which is part of 
newlib which is available on sources.redhat.com.  All linux targets do 
things this way, but they have a lot more complexity than you need for 
an embedded target.
