commit d871d478061f10b0879c688e2fa941407e9137aa

Move elf32.em and elf-generic.em functions
Many ELF linker targets support multiple "emulations" and thus have
multiple copies of elf32.em being compiled and linked into ld. This
patch moves much of elf32.em and elf-generic.em into files which will
be compiled just once, resulting in a 20% decrease in ld size for
--enable-targets=all.
