From 6a8ccc95528f5e86a8770ed15ce89609b5b3dee9 Mon Sep 17 00:00:00 2001 From: Waldemar Brodkorb Date: Wed, 18 May 2016 18:41:24 +0200 Subject: remove linuxthreads.new, rename linuxthreads.old Linuxthreads.new isn't really useful with the existence of NPTL/TLS for well supported architectures. There is no reason to use LT.new for ARM/MIPS or other architectures supporting NPTL/TLS. It is not available for noMMU architectures like Blackfin or FR-V. To simplify the live of the few uClibc-ng developers, LT.new is removed and LT.old is renamed to LT.
