You're telling him that it's possible to build using ...CPU_TARGET=i386 
OS_TARGET=linux but where do those come from? Without being told by a 
developer or without referring to fully updated documentation, how does 
somebody know to use "i386" rather than "x86", or whether it should be 
"mips" or "mipseb"?

I can see that there's a MAKEFILETARGETS list in the makefile, which 
obviously goes slightly further than I'm asking in that it shows the 
valid combinations (i.e. somebody trying to build for powerpc + os2 is 
severely out of luck). But something like a "targets" target would be 
useful.
