I corrected the failure of make dist but it's still broken (some files
not included)

Fixed.

CFLAGS and LDFLAGS should have no such effect. Perhaps you set TARGET_*
variables as well? Those are meant for cross-compiling (and we actualy
cross-compile). Setting them to anything other than the options for
target architecture (in this case i386) would have an unpredictable
effect. And there is no way our build system can check for every
possible annoying parameter. My recomendation is GRUB to be excluded
from any default compile flags at packaging level.
