Hi, Dimitry.
buildworld is failed when WITH_LLDB=
some ports cannot build.
reason1: clang cannot handle some options.
(libmad build)
cc: error: unknown argument: '-fforce-addr'
cc: error: unknown argument: '-fthread-jumps'
cc: error: unknown argument: '-fcse-follow-jumps'

reason2: c++ -std=c++11 detect bad c++ code which older clang cannot detect.
