pthread_initialize is a static function and should not be mentioned in a
header. The #pragma weak for it appears to confuse gcc-4.7.

Use __UCLIBC_HAS_TLS__ instead of USE___THREADS (although this LT implementation
will never support TLS).
Disable unused/unneeded members of the pthread_functions structure.
No redirect/forward for _pthread_cleanup_push/pop, it would have not worked anyway
due to the fact, that the structure member was not initialized. Disable it's possible
internal use in libc-lock.h.
Avoid using internals.h in libc_pthread_init.c (moving a prototype to pthread-functions.h).

sparc target has assembly implementations of clone.S that doesn't
get used, and thus the build breaks. Also, sparc is missing a header file in
pthreads.old that exists in pthreads.new.

A lot of libc code calls the pthread cleanup funcs implicitly (for stdio)
which currently goes through the PLT. Since we already have forwarding
symbols for these funcs, it's safe to declare the internal libc usage
hidden as a loaded libpthread will have the real symbols found.

The pthread_yield() function in linuxthreads does the same thing as the
standardized sched_yield() function, so add a simple define for it to make
porting GNU apps easier.

M5485 processor
1. Disable mmap2() if we're compiling for coldfire and fall back to mmap().
It seems to map a different file area on a 2.6.25 linux kernel.
2. Uses pc-relative addresing[1], computes ADDR_ALIGN, PAGE_ALIGN
and OFFSET_ALIGN relatively to _dl_pagesize[3].
On coldfire/M5485 _dl_pagesize is 0x2000.

gcc version checking in every pt-machine.h header ... while __extern_always_inline should work fine, i think what is intended is __extern_inline ... should double check later

The following patches add support for the Xtensa processor architecture
to uClibc. They are based on a recent SVN checkout (12/05/2007).
The first patch (attached to this post) adds Xtensa support to various
shared configuration and make files. The following patches then include
the Xtensa specific files and directories.
I welcome any feedback and would appreciate it if you could include the
patches into the mainline tree. I am certainly committed to maintain the port.
Bob Wilson was kind enough to review the patches.
Some notes about the architecture: Xtensa is a configurable and
extensible processor architecture developed by Tensilica. For more
information, please visit: www.linux-xtensa.org.

that all entries in the __pthread_functions point to functions within
libpthread, not identically-named functions in libc.
