For some reason your system header files are defining those __sync
symbols but the libc which is being linked against does not contain them.

Please check your system for multiple libc libraries and ensure only one
version is installed (latest by version is best) or that CXXFLAGS is
passed arguments to identify the latest one explicitly.
