haproxy: tweak thread activation

Browse source 
If threads are enabled, as described in include/common/hathreads.h,
haproxy uses __sync_*_4 intrisics if gcc < 4.7. Otherwise, haproxy
uses __atomic_ intrinsics.

As a result, instead of adding a dependency on BR2_TOOLCHAIN_HAS_SYNC_4
and BR2_TOOLCHAIN_HAS_ATOMIC in Config.in, enable threads only if the
dependencies are fulfilled in haproxy.mk

Fixes:
