There are multiple reasons:

Yes, I was confused by LINUX_VERMAGIC which uses files generated during kernel
build, but then
falls back to "unknown" when these are not present.
But the value of LINUX_UNAME_VERSION is used exclusively while installing
modules, so it
would in principle be possible to delay its usage until the kernel has been
built.
- back in the days when trunk supported 2.4 kernels, that file was not present
ok, for 2.4 kernels, we could fall back to the original generation.
- as the comment states in top-level Linux sources, this file might
not be present, and cannot always be relied on
I hadn't been able to find such a comment. In fact what I found is
# Read KERNELRELEASE from include/config/kernel.release (if it exists)
KERNELRELEASE = $(shell cat include/config/kernel.release 2> /dev/null)
and
# Store (new) KERNELRELEASE string in include/config/kernel.release
include/config/kernel.release: include/config/auto.conf FORCE
$(call filechk,kernel.release)
which seem to indicate that the file isn't that unreliable any more.
The reason I am that insistent is, that it would be nice to support all of the
kernel's
version numbering schemes for custom kernels as well, including support for
loading modules
of such a kernel, e.g. the localversion files which are at the moment
officially unsupported
by openwrt.
