- Fix pthread detection
- configure.in always calls AC_CHECK_COMP_OPT(pthread) which succeeds with the
- toolchain used although it does not contain thread support:
- checking for mutex_lock in -lthread ... no
- checking for pthread_mutex_lock in -lpthread... no
- checking for pthread_mutex_lock in -lc... no
- checking if compiler accepts -pthread... yes
- checking for pthread_mutex_lock in -lc... no
- checking for pthread_mutex_lock in -lpthread... no
- This positive configure check leads to
- CFLAGS="$CFLAGS -pthread"
- in ./configure, line 15757 which causes a compilation bug
- /home/br/br4/output/host/opt/ext-toolchain/bin/../lib/gcc/arm-buildroot-linux-uclibcgnueabi/4.8.3/../../../../arm-buildroot-linux-uclibcgnueab
- using this defconfig
- http://autobuild.buildroot.net/results/e86/e86e97ff7887f1bdc6bf913498392ff50f56ea88/defconfig
- This patch disables the freebsd-only code path. Patching configure directly
- prevents the need for autoreconf.
