I didn't try removing just that list; I did rm -rf of the whole
obj/tools/destdir tree.

In your build, is lgpl3/gmp/lib/libgmp built?   It seems the header
isn't installed on purpose.

Do you have a gmp.h in your destdir include?

After running build.sh, I can cd to the failing place and rerun
nbmake-amd64 from the tools bin:

  Stop.
  nbmake: stopped making "all" in /n0/gdt/NetBSD-current/src/external/gpl3/gcc/usr.bin/backend

I don't see how this can succeed, because gmp.h is not installed, and
there is no -I to the not-installed copy.  But I see a gmp.h symlink
which resolves to plausible content, and -I.

Is system.h supposed to have "" instead of <>?

Is the -I. being ignored?  Messed up because of sysroot?   A new feature
of gcc 14 that it works for includes in the file, but not in system
headers?
