11.0-CURRENT powerpc64 cont'd: without adding to LIBADD linking various programs are getting undefined references

A top-post to make this new toolchain material easy to find. To skip to the original material skip down to the "= = =" text. But you may want to read the below for context first.
pkg info reports:
> powerpc64-binutils-2.25.1 GNU binutils for powerpc64 cross-development
> powerpc64-gcc-5.2.0 Cross GNU Compiler Collection for powerpc64
I've been attempting to use only those, not the below compilers/tools.
Also around are:
> binutils-2.25.1 GNU binary tools
> gcc49-4.9.4.s20151125_1 GNU Compiler Collection 4.9
There are no other C/C++ compiler ports present.
The 2015-Apr-18 vintage 11.0-CURRENT I was trying to update has:
> # clang --version
> FreeBSD clang version 3.6.0 (tags/RELEASE_360/final 230434) 20150225
> Target: powerpc64-unknown-freebsd11.0
> Thread model: posix
but does not have gcc 4.2.1 at all. powerpc64-gcc is linked to instead, for example:
> # gcc --version
> gcc (FreeBSD Ports Collection for powerpc64) 5.2.0
> Copyright (C) 2015 Free Software Foundation, Inc.

gcc5 is not around because it and powerpc64-gcc-5.2.0 conflict on at least one file. That is why it is gcc49 as the more general gcc port.
This is a WITH_LIBCPLUSPLUS context.
= = = The original material . . . = = =
Note: After the below examples rescue had a much larger list of Undefined References from various sources. At least for now I've given up and not tried to track down what to add to get rescue to link.
Explicit md references were used to avoid symbol problems in:
/usr/src/cddl/sbin/zfs/Makefile
/usr/src/cddl/sbin/zpool/Makefile
/usr/src/cddl/usr.bin/zinject/Makefile
/usr/src/cddl/usr.bin/zstreamdump/Makefile
/usr/src/cddl/usr.bin/ztest/Makefile
/usr/src/cddl/usr.sbin/zdb/Makefile
/usr/src/cddl/usr.sbin/zhack/Makefile
(A separate submittal covered the first few of those in more detail.)
libcrypto use had similar issues, for example:

Without the addition the result was:

The -L's ending with /.'s are from my /etc/src.conf . They are associated with trying to self-build on a powerpc64 PowerMac using only powerpc64-xtoolchain-gcc's powerpc64-gcc WITH_LIBCPLUSPLUS: powerpc64-gcc is acting as both the host toolchain and the CROSS_TOOLCHAIN. No 4.2.1 gcc is present. I know this is not a usual way of doing things. There may be better ways. But if I manage to expose some missing dependency tracking some good came of it.
And there was the need to add sbuf explicitly for its indirect use, such as for:

Otherwise I got:

I am attempting an update after having been away from the PowerMacs for months.
