The method to resolve the issue would probably be to disallow gas to do any 
fixup work on weak lables. 
Probably one could use the TC_VALIDATE_FIX hook in order to realize this. E.g. 
by adapting an expression like 
 
#define TC_VALIDATE_FIX(FIXP,SEG,SKIP)                      \ 
if (FIXP->fx_r_type == BFD_RELOC_AVR_7_PCREL                \ 
    || FIXP->fx_r_type == BFD_RELOC_AVR_13_PCREL            \ 
    || FIXP->fx_r_type == BFD_RELOC_AVR_LO8_LDI_PM          \ 
    || FIXP->fx_r_type == BFD_RELOC_AVR_HI8_LDI_PM          \ 
    || FIXP->fx_r_type == BFD_RELOC_AVR_HH8_LDI_PM          \ 
    || FIXP->fx_r_type == BFD_RELOC_AVR_16_PM)              \     
  {                                                         \ 
     goto SKIP;                                             \ 
  } 
 
to handle the case that FIXP refers to weak lables. The only question would be, 
how to find out whether or not FIXP refers to a weak label.?  
 
This probably would solve the issue for the avr target. I think, however, that 
the issue should be addressed for all of the targets since I believe it to be 
present also elsewhere.
