domoticz: fix build on powerpc64le

Browse Source 
There is an issue with powerpc64le and boost::uuids::random_generator on the
following line of code (from include/boost/uuid/seed_rng.hpp):
sha.process_bytes( (unsigned char const*)&std::rand, sizeof( void(*)() ) )
This line "inspects the first couple bytes (here eight) of the std::rand
function to seed some rng. Due to the implementation of process_bytes and
inlining happening, it seems that one of the loops therein uses &rand-1 as
some boundary, compiling with -O0 makes that reloc come out as 'rand + 0' and
the link will succeed."
