Subject: [PATCH] e2fsprogs: Add INCLUDES to BUILD_CFLAGS when cross-compiling

We need $INCLUDES in BUILD_CFLAGS otherwise cross-compilation is broken
now that util/subst.c uses config.h (from commit 2873927d15).

I would think that

BUILD_CFLAGS="-I$(top_builddir)/lib -DHAVE_CONFIG_H"

... would be safer, since $INCLUDES could potentially include some
$CPPFLAGS that could be specific to the target architecture.

Yes?

Not really, since that way it's missing config.h, still failing:

-----
cd ./util ; /usr/bin/make subst
make[2]: Entering directory
`/home/gustavoz/b/test/output/build/e2fsprogs-1.42.10/util'
CREATE dirpaths.h
CC subst.c
subst.c:8:20: fatal error: config.h: No such file or directory
compilation terminated.
