make[4]: "/build/armv7/usr/src/sys/conf/kmod.mk" line 234: Malformed conditional (!defined(DEBUG_FLAGS) || ${MK_SPLIT_KERNEL_DEBUG} =="no")

Hello to everyone,

I'm trying to cross-compile the kernel on a different host (with the goal
to apply a patch,but this a different story) :


FreeBSD 13.2-RELEASE-p3 GENERIC amd64

to an armv7 target :


bash

export BASEDIR=/build/armv7

export MAKEOBJDIRPREFIX=/build/armv7/obj

mkdir -p /build/armv7/usr

cd /usr

cp -r src /build/armv7/src

cd /build/armv7

fetch -o if_vtnet.c.patch
https://bugs.freebsd.org/bugzilla/attachment.cgi?id=242127&action=diff

patch -u < if_vtnet.c.patch

cd usr/src

make -j4 -DNO_KERNELDEPEND -DNO_CLEAN buildkernel TARGET_ARCH=armv7
KERNCONF=GENERIC


unfortunately I get these errors :


make[4]: "/build/armv7/usr/src/sys/conf/kmod.mk" line 234: Malformed
conditional (!defined(DEBUG_FLAGS) || ${MK_SPLIT_KERNEL_DEBUG} =="no")

make[4]: "/build/armv7/usr/src/sys/conf/kmod.mk" line 334: Malformed
conditional (defined(DEBUG_FLAGS) && ${MK_SPLIT_KERNEL_DEBUG} != "no")


'cause these errors I can't issue the next command :


# make -DNO_KERNELDEPEND -DNO_CLEAN installkernel TARGET_ARCH=armv7
KERNCONF=GENERIC DESTDIR=$BASEDIR/build


Any idea about how to fix it ? thanks.
