Merge remote-tracking branch 'origin/master' into prelink

* origin/master: (32 commits) libubacktrace: fix backtrace support on arm-eabi, which needs libgcc_eh linked too getaddrinfo.c: fix incorrect check for ERANGE from gethostbyaddr_r getaddrinfo.c: improve code readability. No functional changes string: remove unused variable x86_64: silence warning if !TLS buildsys: prettify ssp.c handling madvise is LINUX_SPECIFIC test_nptl: fix expected result for tst-cputimer[123] test_nptl: fix expected result for tst-clock2 test buildsys: make $(LOCAL_INSTALL_PATH) phony ether_aton: reject invalid input tests: disable ether tests if !HAS_SOCKET inet: add ether_aton testcase sysconf: clock_getres depends on HAS_REALTIME __rt_sigwaitinfo: depends on HAS_REALTIME buildsys: minor fixes in Makefile.arch for C6X buildsys: minor fixes in Makefile.arch for microblaze libubacktrace: enabled for all archs indeed. sparc: don't access fp registers when configured for no fpu libubacktrace: generic implementation based dwarf ...
