>Description:
I tried to cross compile netbsd tools and release from a linux vm, and that worked out without a problem using the commands :
$ ./build.sh -U -O ../netbsd-build -j12 -m evbarm -a aarch64 tools
$ ./build.sh -U -u -O ../netbsd-build -j12 -m evbarm -a aarch64 tools
$ ./build.sh -U -u -O ../netbsd-build -j12 -m evbarm -a aarch64 kernel=GENERIC64
$ ./build.sh -U -u -O ../netbsd-build -j12 -m evbarm -a aarch64 release

Wanted to use my mac m1 instead, so cloned current and ran the above commands again. first three went without a problem.
but when i was to compile the release it errors out like below

i have tried different -j values, no difference.

>How-To-Repeat:
$ git clone https://github.com/NetBSD/src netbsd
$ cd netbsd
and run the commands
$ ./build.sh -U -O ../netbsd-build -j12 -m evbarm -a aarch64 tools
$ ./build.sh -U -u -O ../netbsd-build -j12 -m evbarm -a aarch64 tools
$ ./build.sh -U -u -O ../netbsd-build -j12 -m evbarm -a aarch64 kernel=GENERIC64
$ ./build.sh -U -u -O ../netbsd-build -j12 -m evbarm -a aarch64 release
