Problem with cross building NetBSD in Debian Linux 13

[ssszcmawo <ssszcmawo%gmail.com@localhost>]

Hi there, i'm totally new to NetBSD development and for two days in a
row i've been struggling with building it using build.sh, to be more
precise problem occurs when i'm trying to build release (./build.sh -U
-O ~/obj/netbsd -m amd64 -a x86_64 release) like this,and every time,
roughly 20–30 minutes after starting, errors like these pop up :
  nbmake[9]: stopped making "dependall" in

ERROR: Failed to make release

*** BUILD ABORTED ***

I tried to rebuild tools,to build kernel first and then release,tried
to build distribution instead of release and toggling various flags
but nothing happens. I apologize if I’m doing something incorrectly or
making silly mistakes or I left out any details, just trying to get a
sense of how it works. I would be really appreciate if someone could
guide me through setting up the environment to get this running on
QEMU
