11.0-CURRENT (on powerpc64) WITH_CCACHE_BUILD= : example failure

Mostly just an FYI: This means that for my own purposes I'll tend to avoid WITH_CCACHE_BUILD= for now. . .

Context vintage:

> # freebsd-version -ku; uname -aKU
> 11.0-CURRENT
> 11.0-CURRENT
> FreeBSD FBSDG5C0 11.0-CURRENT FreeBSD 11.0-CURRENT #17 r291745M: Sat Dec  5 08:20:20 PST 2015     root_at_FBSDG5C0:/usr/obj/usr/src/sys/GENERIC64vtsc-NODEBUG  powerpc 1100091 1100091

I took a working make command for buildworld and added

> env CCACHE_DIR=/var/tmp/ccache

and

> WITH_CCACHE_BUILD=

and then tried to repeat the build. The result was:

The make command was:

> env CCACHE_DIR=/var/tmp/ccache make -j 6 \
> WITH_FAST_DEPEND= WITH_CCACHE_BUILD= \
> CROSS_TOOLCHAIN=powerpc64-gcc \
> WITH_LIBCPLUSPLUS= \
> WITHOUT_CLANG_BOOTSTRAP=
> WITH_CLANG= WITH_CLANG_IS_CC= WITH_CLANG_FULL= \
> WITHOUT_CLANG_EXTRAS= \
> WITH_LLDB= \
> WITHOUT_GCC_BOOTSTRAP= WITHOUT_GCC= WITHOUT_GNUCXX= \
> WITHOUT_BOOT= WITHOUT_LIB32= \
> buildworld buildkernel \
> KERNCONF=GENERIC64vtsc-NODEBUG \
> TARGET=powerpc TARGET_ARCH=powerpc64

[Yes, I'm using powerpc64-xtoolchain-gcc/powerpc64-gcc on a powerpc64 machine (PowerMac G5), no gcc 4.2.1 present and clang 3.7 unused for the build: powerpc64-gcc is also in use as a system tool chain, not just as the "self hosted" cross toolchain.]

Removing

> env CCACHE_DIR=/var/tmp/ccache

and

> WITH_CCACHE_BUILD=

and then repeating went back to working again. I actually went back and forth more than once and tested with and without WITH_FAST_DEPEND= as I was experimenting with both. The reported behavior was uniform over this activity.

The ports vintage powerpc64-xtoolchain-gcc/powerpc64-gcc and other things are from:
