 Ah, that's true, but, I see that the *.a files exist in /usr/lib/i386/.
 (Prolly should be removed.)

 Without the base32 set, I see:
 
 ```
 qemu$ uname -a
 NetBSD qemu.local 11.0_STABLE NetBSD 11.0_STABLE (GENERIC) #0: Sun Aug  2 14:10:41 UTC 2026  mkrepro%mkrepro.NetBSD.org@localhost:/usr/src/sys/arch/amd64/compile/GENERIC amd64
 
 qemu$ gcc -m32 -pthread -o pt pt.c -lpthread
 ld: cannot find -lgcc_s: No such file or directory
 ld: cannot find -lgcc_s: No such file or directory
 
 qemu$

 After unpacking the base32 set:
 
 ```
 qemu$ gcc -m32 -pthread -o pt pt.c -lpthread
 
 qemu$ ls -l pt
 -rwxr-xr-x  1 rvp  wheel  20496 Aug  3 22:57 pt
 
 qemu$ ./pt
