This patch introduces optimized versions of memcpy and memset for
frv.

Thanks, this patch implements your suggestion.

A program that requests __pthread_sig_debug to be blocked will
self-deadlock when it requests a thread to be created, because the
debugger (rda or gdb) will never get the signal, so it won't wake up
the pthread manager as expected.
This patch fixes it.

Oops, this adds the page alignment offset to the mprotected size.

ld.so mprotect rwx .dyanmic segment for mips DT_DEBUG
Allow writing debug_addr into the .dynamic segment.
Even though the program header is marked RWE, the kernel
gives it to us rx.

If I change that ELF_RTYPE_CLASS_COPY to ELF_RTYPE_CLASS_PLT to tell
_dl_find_hash to ignore stubs when resolving undefined functions without
stubs, the dlopen tests all pass. dlopen gets a pointer to the libc.so
malloc instead of a pointer to the libpthread malloc stub. Yay! :-)

Add timegm() function.
Make lookup_tzname() static (as it should have been).
Have strftime() get timezone information from the passed struct
for the %z and %Z conversions when using struct tm extensions.

Also fix the sizeof() issue since the change to a dynamicly allocated buf.
Note! This is still broken wrt threading, but so is the glibc version.
I'm just commiting this for new until I can test my rewrite.

The vfork() wrapper defined in libpthread, that's used to run
pthread_atfork()-registered handlers, is not only a very bad idea,
it's broken and useless. Here's the rationale:
[---------snip----------]
Since the implementation as it stands is broken (linking a program
that vfork()s and exec()s on the child and wait()s on the parent works
unless you happen to link with libpthread), and I can't think of
any workable solution, I suggest that we simply remove the vfork()
overrider in the non-MMU case. Yes, we might lose some small amount
of functionality here, but it's not like people running uClinux expect
anything resembling actual fork() to work.

Because variables are linked to fixed registers, there is a problem in :
(*__errno_location())=(-_r0);
As __errno_location() uses r0 to return the address of the errno location,
the negated address will be assigned instead of the error code.
Attached patch will resolve this.

This code in uClibc would attempt to set the default facility if
none was specified. Except none being specified is 0, which is
also LOG_KERN, therefore klogd could never get kernel messages
logged as LOG_KERN.

This patch arranges for the .so files in say /usr/lib to be soft links
to ../../lib, instead of to /some/arbitrary/pathname/lib. This
enables seamless relocation of a toolchain containing the development
and run time trees in a sys-root.

I added this function after I posted the last version of the FR-V

instead. Based on an initial patch from Tobias Anderberg, but reworked. I
asked Tobias to look into doing something more like what is done in busybox,
but that proved to be a pain.
One possible concern is that these buffers will probably show up as
memory leaks i.e. with valgrind. Perhaps we should add in an atexit
call to free this memory right after we allocate it?

Hi
I just noticed that gcc has an "b"(Address base register) operand that
will match all "r" registers but r0. It is a better fix then adding
r0 to the clobber list.
What do you think?

error.c file still needs work.
