Would this be testable on powerpc-apple-darwin8?

The -mcpu=8540 -msdata=eabi option is important.  I don't know how to trigger

this bug without the -mcpu=8540 option.

The problem is that something in GCC calls default_elf_select_section(decl,

reloc, align) with categorize_decl_for_section(decl, reloc) == SECCAT_SRODATA. 

This in turn calls get_named_section
