>Description:
Hello, I am a newbie of building NetBSD and I want to cross-compile NetBSD sparc64 on my macOS(M2) chip.

(1) My macOS environment:
$ uname -a
Darwin nanxiaos-MacBook-Pro.local 24.6.0 Darwin Kernel Version 24.6.0: Mon Jul 14 11:30:51 PDT 2025; root:xnu-11417.140.69~1/RELEASE_ARM64_T8112 arm64

(2) I use NetBSD trunk branch:
$ git rev-parse HEAD
fbc738f7c1fa595c6a6b1d5ff86a9d722bf90af8

(3) Use following command to cross-compile:
$ ./build.sh -O ../obj -U -u -m sparc64 -N1 -j4 release
......
sparc64--netbsd-gcc: internal compiler error: Segmentation fault: 11 signal terminated program cc1
Please submit a full bug report, with preprocessed source (by using -freport-bug).
See <http://www.NetBSD.org/support/send-pr.html> for instructions.
