Similar to musl libc a single libc has many benefits and solves
some open issues with uClibc-ng.
- no pthread_mutex_* weak symbols exported anymore
- applications no longer failing to link when either
-lrt or -lpthread are missing for dynamic and static linking mode
- smaller C library
- slightly better runtime performance

Do not pollute libraries with its own implementation of __aeabi_unwind_cpp_pr1 code.
Just add it to uclibc_nonshared.a archive and share it.
This fixes build issue with static linking of application due to multiple symbol
definition in libgcc_eh-a and libpthread.a or librt.a

The SSP_ALL_CFLAGS in nptl arch CFLAGS leaks out and forces things
like dl-support.c, brk.c, sbrk.c memcpy, etc to be built with
-fstack-protector-all. This is bad when linking statically since
initializing TLS will call those functions before SSP is initialized.
The libpthread itself will still be built with -fstack-protector-all
due to CFLAGS-nptl has SSP_ALL_CFLAGS in libpthread/nptl/Makefile.in
Thanks to Timo Teras for helping with this.

Now automatically picks the correct (arch and subarch specific) impls in
favour of generic impls.
make O=/tmp/objs PREFIX=/my/sysroot -j
works now as expected (both out-of-tree as well as parallel-safe).

* Introduce pregen-headers-y which is list of generated headers
during the build and add this to pregen target in top level makefile.
Also add nptl_headers, nptl_arch_headers, nptl_linux_headers
to this if compiling with nptl.
* Replace pthread_pregen var with pregen-headers-y.
* Make nptl_headers, nptl_arch_headers, nptl_linux_headers variables
instead of sub targets.

gets rid of nptl_headers,nptl_arch_headers,nptl_linux_headers targets
also, clean up extra slashes in i386/sparc and unify the implementation
of nptl header generation between all archs
