Automatic patching via two oneliners by Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>:
sed -i -e 's/[[:space:]]pt-vfork\.[csS]//' -e '/^ASFLAGS-pt-vfork\./d' $(git grep -l pt-vfork libpthread/nptl/sysdeps)
find libpthread/nptl -name "*pt-vfork*" -exec git rm {} \;

This matches a similar change made to glibc.
No functional changes here.

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).

The libc stubs should never override the libpthread provided
functions inside libpthread, otherwise the struct pthread_functions
that is used by the forwarder stubs goes bad.

This reverts most of commit 1610762362e651f86ca284ac59a1d7ec88034e4e.
Marking the symbols hidden is wrong, because libc accesses
the pthreads internal symbols for internal locking.

Add attribute_hidden to all symbols having libc forwarder. This prevents
recursive self calls which would happen if libc is before libpthread in
linking order: the forwarder functions would call itself via the function
table, since the libpthread symbols would get overwritten with libc ones.
This has not been a problem in glibc since there these symbols are marked
hidden with linker version-script. Since we don't use one, we need to mark
these explicitly.

Based on Peter Mazinger's comments on a recent commit, I decided
to get rids of all occurrences of PIC changing them to __PIC__
