That's probably "supported by default". I'm sure it's possible to  
still build a binutils version that still supports regular elf_x86_64.

My suggestion would be to simply change the compiler to always use  
elf_x86_64_sol2/elf_i386_sol2 and require binutils 2.21 or higher on  
Solaris. It's not like there is a massive user base for that platform,  
nor very old Solaris/x86 systems that will have trouble supporting  
newer binutils versions.

Apparently the Solaris ABI is in fact different from the regular x86  
ELF abi, which is why that change was made in the first place. So the  
programs generated with -melf_x86_64/-m-melf_i386 were not properly  
ABI-compliant in the first place.
