My solution to this has always been to make a cross compiler environment (even if it is the same processor family). Thusly i386-linux-gcc knows that the target system's include files are in:
/usr/local/<project>-tools/i386-linux/include (/linux, /asm)
The other advantage to this is that I can switch my host environment (within reason - compatible host glibcs, ok) and not have to change the target compiler.
