[yocto] solve gcc-5.0.0 build errors with "-P" option to cpp?

[Robert P. J. Day]

  as i mentioned recently, using fedora rawhide and having recently
upgraded to gcc-5.0.0, some packages (eg., ncurses-native) failed to
build for this reason:

 https://gcc.gnu.org/bugzilla/show_bug.cgi?id=60723

toward the bottom (comment 27), jakub jelinek suggests the solution of
simply telling people to preprocess with "-P", which inhibits the
generation of line markers.

  so i just added a wide-sweeping:

CPPFLAGS_append = " -P"

to my local.conf and, sure enough, that got around the build error(s).
is that the best workaround for the time being until this weirdness
with gcc-5.0.0 is fixed?
