errno, h_errno: correct them for non-TLS
Move h_errno related stuff to separate file. Do not hide errno and h_errno for non-TLS, else it keeps being 0. Make __[h_]errno_location weak for non-TLS. Signed-off-by: Peter S. Mazinger <ps.m@gmx.net> Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
