There is one more reason for CROSSDEBUG, which is CROSSDEBUG=split (or 
split-dwarf), causing build system to create separated symbol files for 
cross compiled modules. This does not translate so well to EXTRACFLAGS, 
it's handled by makedep. We currently don't do similar things for ELF 
files. The common practice in Unix world seems to be splitting 
executables at install time. Given additional portability challenges, 
I'm not sure if providing an equivalent of CROSSDEBUG=split for ELFs is 
worth it.


How about an easier solution: we could skip appending -gdwarf-2 if any 
of -gdwarf-[234] options are provided in CFLAGS.
