>Description:
On pkgsrc-2025Q2 emulators/qemu build fails on NetBSD/i386 10.1.

>How-To-Repeat:
 https://releng.netbsd.org/pkgreports/shadow/2025Q2/NetBSD-10.0-i386/20250805.0724/qemu-10.0.2/install.log

>> => Setting PaX MPROTECT flags
>> paxctl: Can't open `/pbulk/work/emulators/qemu/work/.destdir/usr/pkg/bin/qemu-system-aarch64': No such file or directory
>> *** Error code 1

>Fix:
Exclude LP64 targets on ILP32 hosts, i.e. enable LP64 targets only
on LP64 hosts?

(not confirmed how qemu configures targets on each host
 but the following patch works around on NetBSD/i386 10.1)
