> With the legacy build system MODULE_CFLAGS can be set to pass compiler
> flags specific for the kernel modules builds.
> This is used currently by Ubuntu and Debian.
> Set ccflags-y in the Kbuild to achieve the same result with Meson, and to
> keep backward compatbility with older scripts.
> 
> Fixes regression in Ubuntu/Debian when the Kbuild is included in the DKMS
> source package, as DKMS will pick it up silently by default if present,
> causing the MODULE_CFLAGS to be ignored.

> Fixes: a52f4574f798 ("igb_uio: build with meson")
