things, and avoid potential deadlocks caused when a thread holding a uClibc
internal lock get canceled and terminates without releasing the lock. This
change also provides a single place, bits/uClibc_mutex.h, for thread libraries
to modify to change all instances of internal locking.

linuxthreads[_db] as well, don't try on slow box

libc.a/libc.so, the diffs go into libc-static-y/libc-shared-y exclusively, add IMA to libc, don't use any MSRC anymore

libc-a-y for objects that go into static libs, changing their suffix to .os, of they should be PIC

archs lack proper crt1. The Makefiles in extra/scripts are intended to be linked into each dir, where it is necessary to build locally.

objects at once; use :=//$</$^; use CRT_SRC/CRT_OBJ/SCRT_OBJ/CSRC/COBJ/SSRC/SOBJ/MSRC/MOBJ where no more is needed, if only CSRC is present use OBJS directly instead of COBJ; CTOR_TARGETS are created directly in lib; remove unused/unneeded parts. Hope I haven't broken too much.

but they do no harm for the linuxthreads case. Yes, I tested this.

Hi Erik
It seems to me that __pthread_once and __pthread_initialize_minimal could be made
WEAKs with no stub. The code in rpc_thread.c and __uClibc_main.c appears to expect this.
Also, __pthread_return_0 __pthread_return_1 and __pthread_return_void can be static, not to
pollute the name space.

missing one in the glibc abi, and including a number of extras (which I
left in commented).
Unfortunately, this brings back the perl pthread bug. Fixing the incorrect
weaks in libpthread wasn't sufficient to escape the shared loader bug. :-(

were including libc-lock.h which had a bunch of weak pragmas. Also,
uClibc supplied a number of no-op weak thread functions even though
many weren't needed. This combined result was that sometimes the
functional versions of thread functions in pthread would not override
the weaks in libc.
While fixing this, I also prepended double-underscore to all necessary
weak thread funcs in uClibc, and removed all unused weaks.
I did a test build, but haven't tested this since these changes are
a backport from my working tree. I did test the changes there and
no longer need to explicitly add -lpthread in the perl build for
perl to pass its thread self tests.

rm.patch:
* Define $(RM) as rm -f in Rules.mak and test/Rules.mak
(this is the same definition as gmake uses by default).
* Change all occurrences of rm and rm -f into $(RM).

glibc 2.1.3 and ported to work with uClibc by Stefan Soucek and Erik Andersen
(me). Stefan has hacked things up such that linuxthreads runs on MMU-less
systems (tested only on arm-nommu). Erik cleaned things up and made it work
properly as a shared library.
