Subject: configure: don't pass -Waddress to ObjC compiler on OSX when compiling osxvideosink
X-Git-Tag: 1.19.3~509^2~7136^2~598

configure: don't pass -Waddress to ObjC compiler on OSX when compiling osxvideosink

Temporary workaround until we fix this properly and check for
the ObjC warning/error flags instead of just passing CFLAGS to the
ObjC compiler.
