./configure --enable simulator pass without error.

make exited with error when linking classicladder.
Some bad code is in socket_modbus_master.o.
socket_modbus_master.c is compilling, but not linking.

Message is

Linking classicladder
/usr/bin/ld: objects/hal/classicladder/socket_modbus_master.o: undefined reference to symbol 'pthread_create@@GLIBC_2.2.5' /usr/bin/ld: note: 'pthread_create@@GLIBC_2.2.5' is defined in DSO /lib/x86_64-linux-gnu/libpthread.so.0 so try adding it to the linker command line /lib/x86_64-linux-gnu/libpthread.so.0: could not read symbols: Invalid operation

make: *** [../bin/classicladder] B?a;d 1
make: Opuszczenie katalogu `/opt/linuxcnc.sim/src'

(symbol is pthread_create<at><at>GLIBC_2.2.5)

I have compilled linuxcnc in January, on this same system but earlier version of system libraries.
libpthread.so.13 not libthread.so.15.
