avoid linker warnings with the new binutils by not forcing ld.elf_so
...
to be soft-float. the floating-point usage in ld.elf_so is only
because of stdarg functions like printf(), and gcc 4.5 is good
about not actually executing the FP instructions in such functions
unless FP values are passed to them, which ld.elf_so doesn't do.

Introduce a new type Elf_Symindx for use in decoding the symbol hash table
...
section and allow this type to be overridden.
The ELF specification says it should always be uint32_t (Elf_Word), but
alpha decided to be different (not sure why). Define Elf_Symindx to be
uint64_t on alpha.
Alpha no longer uses non-standard definitions of Elf64_Sword and
Elf64_Word. Remove the ability to override these types.
Fixes ld.elf_so after Herculean effort from me and martin.
