Hide gnu extension warnings in log/log.h
system/core/include is included in the global include path using
-isystem, which hides all warnings. Fix warnings in log/log.h
in preparation for moving from -isystem to -I.
log/log.h uses gnu extensions for zero-argument variadic macro token
pasting, which clang warns about with -Weverything. Hide the warnings
using pragmas.
Test: m -j native
