I'm not sure, perhaps something in the cross assembly toolchain is buggy?

In any event, comparing elfdumps from both files shows these dtrace symbols to
be the same:

$ elfdump -s resource.o.gas.2.25.1 |grep dtrace
      [64]  0x00000000 0x00000000  NOTY GLOB  D    0 IGNORE        
__dtrace_Xserver___resource-alloc
      [67]  0x00000000 0x00000000  NOTY GLOB  D    0 IGNORE        
__dtrace_Xserver___resource-free

$ elfdump -s resource.o.gas.2.26 |grep dtrace
      [64]  0x00000000 0x00000000  NOTY GLOB  D    0 IGNORE        
__dtrace_Xserver___resource-alloc
      [67]  0x00000000 0x00000000  NOTY GLOB  D    0 IGNORE        
__dtrace_Xserver___resource-free

I'm running a recent OmniOS 'bloody' 151017 (SunOS 5.11) from 
http://omnios.omniti.com/wiki.php/Installation

If this were a more apparent link time issue I'd suspect compatibility
issues with recent binutils, as has already been discovered with 2.26,
but this is still at compile/assembly time.

Is there some extra verbosity I can turn on in the assembler?
