modpost: propagate W=1 build option to modpost
commit 20ff36856fe00879f82de71fe6f1482ca1b72334 upstream.
"No build warning" is a strong requirement these days, so you must fix
all issues before enabling a new warning flag.
We often add a new warning to W=1 first so that the kbuild test robot
blocks new breakages.
This commit allows modpost to show extra warnings only when W=1
(or KBUILD_EXTRA_WARN=1) is given.
