Patch from Stefan Allius and Edie C. Dost to add SuperH

shared library support.  This also adds some cleaner error
handling, which I (Erik) then ported over to x86 and arm.
In addition Stefan added the following fixes:

- in hash.c was the lvalue handling of global library functions wrong.
   To fix this I had to change the prototype of _dl_find_hash. (==> TIS and
   ELF spec. Vers. 1.2)

- in ldso.c was the order of the .init sections calls wrong. Before we call
  the initialization code of a library we have to check that all dependend
  libraries are already initialized. This can easily made by calling it in the
  revers loading order. For this I added a previous pointer chain.

- in ldso.c the ELF magics wasn't checked fo PPC, MIPS and SH architecture
