I have a feeling that you will find that ELFOSABI_SOLARIS isn't actually used,
and Solaris just declares itself as "System V" (ie ELFOSABI_NONE).  If it were, 
I guess elf_elfheader(output_bfd)->e_ident would be the place to go looking for 
it.

You might do better to create a new linker emulation, have it override the 
contents of the .interp section, and make that the default for Solaris.  That 
way the hackery is localised inside ld, rather than involving BFD itself.

(Personally I don't think I'd bother: there are several other targets where GNU 
ld will get the interpreter location wrong if it's left to its own devices, 
and GCC has to include an appropriate -dynamic-linker option in the specs 
file.)
