powerpc64-xtoolchain/powerpc64-gcc lacks lib32 support, so fails boot1.elf link (for example)

For an amd64 11.0 context with powerpc64-xtoolchain-gcc in place: doing
make -j 7 CROSS_TOOLCHAIN=powerpc64-gcc \
-DWITHOUT_GCC -DWITHOUT_GCC_BOOTSTRAP -DWITHOUT_GNUCXX \
-DWITHOUT_CLANG -DWITHOUT_CLANG_BOOTSTRAP -DWITHOUT_CLANG_FULL -DWITHOUT_CLANG_IS_CC \
-DWITHOUT_CLANG_EXTRAS -DWITHOUT_LLDB \
buildworld buildkernel KERNCONF=GENERIC64-NODBG \
TARGET=powerpc TARGET_ARCH=powerpc64
the result is the following during WITH_BOOT's build activity:
--- boot1.elf ---

This is from there being no lib32-like libgcc or its use from what I can tell. For example a normal gcc 4.2.1 build WITH_LIB32= has the following that a CROSS_TOOLCHAIN=powerpc64-gcc does not have:
. . .
--- _lib-eh-install ---
sh /usr/src/tools/install.sh -C -o root -g wheel -m 444 libgcc_eh.a /usr/obj/powerpc.powerpc64/usr/src/lib32/usr/lib32
. . .
--- _lib-eh-install ---
sh /usr/src/tools/install.sh -C -o root -g wheel -m 444 libgcc_eh.a /usr/obj/powerpc.powerpc64/usr/src/lib32/usr/lib32
sh /usr/src/tools/install.sh -C -o root -g wheel -m 444 libgcc_eh_p.a /usr/obj/powerpc.powerpc64/usr/src/lib32/usr/lib32
--- _libinstall ---
sh /usr/src/tools/install.sh -s -o root -g wheel -m 444 libgcc_s.so.1 /usr/obj/powerpc.powerpc64/usr/src/lib32/usr/lib32
sh /usr/src/tools/install.sh -l s libgcc_s.so.1 /usr/obj/powerpc.powerpc64/usr/src/lib32/usr/lib32/libgcc_s.so
. . .
--- _lib-eh-install ---
sh /usr/src/tools/install.sh -C -o root -g wheel -m 444 libgcc_eh.a /usr/obj/powerpc.powerpc64/usr/src/lib32/usr/lib32
sh /usr/src/tools/install.sh -C -o root -g wheel -m 444 libgcc_eh_p.a /usr/obj/powerpc.powerpc64/usr/src/lib32/usr/lib32
. . .
--- gnu/lib__L ---
sh /usr/src/tools/install.sh -s -o root -g wheel -m 444 libgcc_s.so.1 /usr/obj/powerpc.powerpc64/usr/src/lib32/usr/lib32
sh /usr/src/tools/install.sh -l s libgcc_s.so.1 /usr/obj/powerpc.powerpc64/usr/src/lib32/usr/lib32/libgcc_s.so
Some of which would be assocaited with the -m32 use in (for a normal gcc 4.2.1 based build):
--- boot1.elf ---
cc -ffreestanding -msoft-float -Os -I/usr/src/sys/boot/powerpc/boot1.chrp/../../common -I/usr/src/sys/boot/powerpc/boot1.chrp/../../../ -D_STANDALONE -m32 -mcpu=powerpc -m32 -mcpu=powerpc -std=gnu99 -nostdlib -static -Wl,-N -Wl,-m -Wl,elf32ppc_fbsd -Wl,-m -Wl,elf32ppc_fbsd -o boot1.elf boot1.o ashldi3.o syncicache.o
The failing powerpc64-xtoolchain-gcc case lists the following when -Wl,-M,--verbose is used:
--- sys.all__D ---
/usr/local/bin/powerpc64-portbld-freebsd11.0-gcc -isystem /usr/obj/powerpc.powerpc64/usr/src/tmp/usr/include -L/usr/obj/powerpc.powerpc64/usr/src/tmp/usr/lib --sysroot=/usr/obj/powerpc.powerpc64/usr/src/tmp -B/usr/local/powerpc64-freebsd/bin/ -ffreestanding -msoft-float -Os -I/usr/src/sys/boot/powerpc/boot1.chrp/../../common -I/usr/src/sys/boot/powerpc/boot1.chrp/../../../ -D_STANDALONE -m32 -mcpu=powerpc -m32 -mcpu=powerpc -std=gnu99 -nostdlib -static -Wl,-N -Wl,-m -Wl,elf32ppc_fbsd -Wl,-M,--verbose -Wl,-m -Wl,elf32ppc_fbsd -Wl,-M,--verbose -o boot1.elf boot1.o ashldi3.o syncicache.o

so powerpc64-xtoolchain and its powerpc64 do not have any lib32 specific search areas populated but for /usr/lib32: none powerpc64 specific.

The following is my personal, local workaround for /usr/src/lib/csu/powerpc64/Makefile forcing use of the gcc command even when the context does not have one.
