That would not be difficult at all. One could agree on the name of some 
section that contains data for the fuses and the lock-bits. One would do 
something like:

#define SET_FUSE_BITS(F1,F2,F3,L) unsigned char fuses[4] __attribute___ 
((section (".fuses"))) = {F1,F2,F3,L};

The more time-consuming thing would be to teach your favorite programming tool 
to actually use the data in the .elf file.
