commit: http://git.uclibc.org/uClibc/commit/?id=c09e41ef92e48356e62c795384864ee792ac7fe6
branch: http://git.uclibc.org/uClibc/commit/?id=refs/heads/master

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:
