Merge remote-tracking branch 'origin/master' into prelink
* origin/master: (61 commits) fts: fix warning due to old-style function definition ldso_tls: fix compiler warning due to missing cast resolv: fix bug in res_init with ipv6 nameservers config: Fix passing defconfig args buildsys: pt-initfini.s depends on uClibc_config.h libdl: search for ELF_RTYPE_CLASS_DLSYM in dlsym() resolv: try next server on SERVFAIL getaddrinfo: allow numeric service without any hints bump version to 0.9.33-git nptl/pthread: Correct path for machine specific pt-initfini.c ctor/dtor nptl: Fix init and fini function compilation Rules.mak: Rearrange appending UCLIBC_EXTRA_CFLAGS to CFLAGS ARM: remove EABI/OABI selection ARM: detect BX availibility at build time ARM: #include <bits/arm_asm.h> where __USE_BX__ is used ARM: transform the EABI/OABI choice into a boolean ARM: remove sub-arch/variants selection from menuconfig ARM: introduce blind options to select & force THUMB mode ARM: reorder "Use BX" option Fix __libc_epoll_pwait compile failure on x86 ...
