Follow glibc commit 6d96f5e4c0 Solves __lll_timedlock_wait busy-wait issues described at http://sourceware.org/bugzilla/show_bug.cgi?id=15119 Signed-off-by: Leonid Lisovskiy &lt;lly.dev(a)gmail.com&gt; commit 361f679c652647cdea4d5a66999a4b96c1653576 Author: Leonid Lisovskiy &lt;lly.dev(a)gmail.com&gt; Date: Sun May 29 10:06:55 2016 +0300 linuxthreads.old: Fix segfault when pthread_mutex_unlock() called against unlocked NORMAL mutex. Althought, it is undefined behavior, there is no reason for segfault. Program received signal SIGSEGV, Segmentation fault. __pthread_unlock (lock=lock@entry=0x804b03c <lock+16>) at libpthread/linuxthreads.old/spinlock.c:231 231 (&lock->__status, oldstatus, (long)(thr->p_nextlock) & ~1L)) It occurs only on platforms which has HAS_COMPARE_AND_SWAP defined. Restore glibc commit fbaf6e72d6 "spinlock.c (__pthread_unlock): Don't crash if called for an untaken mutex." behavior, broken later by commit 4ad1d0cfbf. Signed-off-by: Leonid Lisovskiy &lt;lly.dev(a)gmail.com&gt; commit 8b28fc50a3891f823531aa276008e1b1b17e0a79 Author: Leonid Lisovskiy &lt;lly.dev(a)gmail.com&gt; Date: Tue May 31 21:43:49 2016 +0300 tests: Take in account Makefiles that have meaning for rebuild only. Currently, targets dependancy list don't include Makefile.in, this leads to incomplete rebuild after target's compiler/linker flags was changed. Use "$(wildcard)" function due to Makefile.in could be absent in subdirectory.
