Hmm. Looking around shows stand/powerpc possibly
not using libsa* at all:

# grep -r stand/libsa /usr/src/stand/ | grep -v "BSD[(:]" | more
/usr/src/stand/userboot/userboot/Makefile.depend:       stand/libsa \
/usr/src/stand/efi/boot1/Makefile.depend:       stand/libsa \

# grep -r SRCS /usr/src/stand/powerpc/

/usr/src/stand/powerpc/ofw/Makefile:SRCS+=              ofwfdt.c

(My patch is omitted above.)

So Warner's note would seem to be asking for a bigger
reorganization for stand/powerpc/*/

I'll note that building for amd64, aarch64, armv7, powerpc64,
and powerpc it was only powerpc* boot1.chrp that failed
historically. But I've not built for all architectures.



ashldi3.c in stand/powerpc/boot1.chrp/Makefile would
overlap with stand/libsa/Makefile also listing it as
stands:

.if ${MACHINE_CPUARCH} == "powerpc"
.PATH: ${LIBC_SRC}/quad
SRCS+=  ashldi3.c ashrdi3.c lshrdi3.c
SRCS+=  syncicache.c
.endif

The same for syncicache.c .
