Try setting KBUILD_OUTPUT in /etc/make.conf — it will be used by
linux-info.eclass (and linux-mod.eclass) automatically, so most kernel
module-compiling ebuilds will do the right thing. There are
exceptions, such as the VirtualBox packages above, which want access
to the build tree outside module compilation for whatever reason, but
I already found a fix for that specific problem
(--with-linux=${KV_OUT_DIR}), so count me as a fan of O=.
You can also apparently set KERNEL_DIR to something other than
/usr/src/linux, but with "eselect kernel" available, this variable is
probably best left alone.
