[Buildroot] [git commit] haproxy: put back dependency on __sync_*_4

[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=443c21ec373a35e8d5a0c8750f6ed2312623b27e
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

__sync_*_4 intrinsics is used by common/hathreads.h when gcc < 4.7 but
also by contrib/tcploop.c or include/proto/shctx.h so put back a
mandatory dependency on BR2_TOOLCHAIN_HAS_SYNC_4 which has been
wrongly removed by commit f22fca4bf27f884950dd7804020e5d5193b570b9
("haproxy: tweak thread activation").

Fixes:
