   Thanks; it's the linker hash table that I want.  I noticed the use
   of static data (mips_elf_text_section, etc.) in mips32-elf.c, and I
   didn't want to perpetuate this.

That particular bit of static data is sort of OK because it is always
set to the same value.  It could be an initialized const, actually.
