>Description:
I tried to remove "COMPAT_40" from NetBSD/amd64 kernel configuration because
there aren't any old binaries on the system and I prefer a kernel without
SA support. Unfortunately this breaks the build:

      link  COLWYN.64/netbsd
/src/tools/bin/x86_64--netbsd-ld -Map netbsd.map --cref -T 
/usr/src/sys/arch/amd64/conf/kern.ldscript -Ttext 0xffffffff80100000 -e start 
-X -o netbsd ${SYSTEM_OBJ} ${EXTRA_OBJ} vers.o
netbsd32_netbsd.o: In function `netbsd32_mount':
/usr/src/sys/compat/netbsd32/netbsd32_netbsd.c:395: undefined reference to 
`compat_40_sys_mount'
netbsd32_sa.o: In function `netbsd32_sa_register':
/usr/src/sys/compat/netbsd32/netbsd32_sa.c:144: undefined reference to 
`dosa_register'
netbsd32_sa.o: In function `netbsd32_sa_stacks':
/usr/src/sys/compat/netbsd32/netbsd32_sa.c:187: undefined reference to 
`sa_stacks1'
*** [netbsd] Error code 1

>How-To-Repeat:
Comment out "COMPAT_40" in the "GENERIC" kernel configuration and try to
build it.

>Fix:
Not known yet.
