For sh64 we need implicit access to the symtab, primarily to get at the
->st_other value. This presently isn't possible, as PERFORM_BOOTSTRAP_RELOC()
is invoked as such:
PERFORM_BOOTSTRAP_RELOC(rpnt, reloc_addr, symbol_addr, load_addr);
while we can easily get the symtab_index value from rpnt->r_info, this still
doesn't buy us easy access to the actual table. As such, I've modified
PERFORM_BOOTSTRAP_RELOC() to take an additional SYMTAB argument. Most
architectures aren't going to care about this, but unfortunately we don't
have any other options for sh64.
The following patch fixes up the API for what we need for sh64, and updates
the other architectures appropriately.

under the LGPL. I noticed Steven J. Hill has accidentally changed the license
to be GPL. Per email with him, change it back to LGPL.

Yes. Feel free to change it.

Move all configuration options into the new config system.

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

out page alignment issues. As we we were assuming 4k pages, which
need not be the case...

Uh, this patch fixes a few bugs that I overlooked. Shoot, even BusyBox
wouldn't work until these are applied. Erik, plop this into CVS please.
Thanks.

I am very pleased to announce that the MIPS dynamic linker/loader
for uClibc is now working. It works on big and little endian
platforms.
A few minor changes were needed to avoid breaking ldd, and since this
makes some non-trivial changes, I have tested on x86, arm, and powerpc
to be sure thoese arches didn't get broken. Excellent work Steven!

complete, but off to a fine start.
