A `release' build on Ubuntu 26.04.1 completed successfully. I did the same on
Pop!_OS 22.04 in QEMU, and that too compiled GMP successfully, but, the build
didn't complete due to lack of space.

Pop!_OS details:

```
$ cat /etc/lsb-release

```

The 2nd config.m4 is created by configure during the tools build phase. The
1st is copied from the pre-generated files in the source, as martin@ pointed
out:

```
rm -f /home/user/workspace/netbsd-11-obj/external/lgpl3/gmp/lib/libgmp/config.m4 &&
cp /home/user/workspace/netbsd-11-src/external/lgpl3/gmp/lib/libgmp/arch/x86_64/config.m4 \
   /home/user/workspace/netbsd-11-obj/external/lgpl3/gmp/lib/libgmp/config.m4
```

Can you:

1. check if `netbsd-11-src/external/lgpl3/gmp/lib/libgmp/arch/x86_64/config.m4'
   and `netbsd-11-obj/external/lgpl3/gmp/lib/libgmp/config.m4' are the same?

2. cat(1) `netbsd-11-obj/tools/gmp/build/config.m4'?

3. retry after wiping the object dir?
