Revert "sparc: use HIDDEN_JUMPTARGET for errno"

This reverts commit f51fb26dbcceee9e48d10facc830bd4a549f6cc2.

This fixes linking error for sparc build.
While building a sparc system you get following linking error:
libc/sysdeps/linux/sparc/pipe.S:54: undefined reference to `__GI___errno_location'

Removing the HIDDEN_JUMPTARGET fixes the issue, while using gcc 4.8.3/binutils 2.24.

The definition of __errno_location was changed recently here:

Revert "sparc: disable cancellable system, as it fails in strange ways right now"

This reverts commit 1db4f8f8389f6a935ecd83aff7fcce5d1cf2c0f3.

It is unclear in which way this is breaking sparc systems.
With this change added you get following linking error:
libpthread/nptl/libpthread_so.a(pt-system.oS): In function `__libc_system':
libc/stdlib/system.c:64: undefined reference to `__wait4_nocancel'

sparc: add missing pthread_spin_lock/pthread_spin_trylock

tst-spin1.c compile breaks with:
test/nptl/tst-spin1.c:34: undefined reference to `pthread_spin_lock'

pthread_spin_lock and pthread_spin_trylock is missing while
building sparc. add the meta c files here.

test: do not depend on compile

When you cross-compile the testsuite and then try to run
on a system without gcc/binutils it would be nice if no compiling
or linking is tried. Refresh test/README (suggested by Khem)

test: get out of the endless while loop, when bind failed

When bind() fails in this test, then /tmp get filled up with
temp files and upcoming tests will fail, because they need to create
temp files, too. Better exit from the loop.
Test still needs to be investigated to fix the failing bind().

test: sync with glibc, use do_test

This breaks out of a deadlock, which occurs when testing for powerpc. (qemu)
Otherwise the test suite does not finish.
