To compile Haproxy 1.8 with threads, at least GCC 4.7 is needed.
CentOs 6 only ships GCC 4.4.7, therefor compilation fails.
You can disable thread support, by adding USE_THREAD= to the make
command (nothing comes after the equal sign):

make clean; make TARGET=linux2628 USE_OPENSSL=1 [...] USE_THREAD=
