We do not support building a HEAD kernel on a RELENG_ box. Never have.
That it usually works for you is just gravy.
The documented minimal steps to build a HEAD kernel is:
make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE

Building a HEAD kernel on RELENG_ isn't anywhere near a supported
configuration. I really don't know where you got the idea it was. On a
6.0-beta2 machine I just did a HEAD 'make kernel-toolchain' - it took
3m53.49s and allowed me to build a HEAD kernel just fine.

I'm afraid that is unreasonable to do in this case. I'd be waiting an
undetermined amount of time for RELENG_6 to thaw before I could do this
work. HEAD was already frozen for 1 months this year - you're
effectively asking me to work as if is frozen for an additional 2 months.
On top of that - the "relevant branches" is HEAD and only HEAD. Which
is where the GCC fixes were committed before depending on them.
Note that I did the RELENG_5 MFC for you personally, knowing you do try
to build HEAD kernels on RELENG_*. I would have MFC'ed to RELENG_6 for
your benefit, but its frozen. You are an RE - please feel free to MFC
the bug fix. I certainly would not mind. :-)
