If the length of $(VERSION).$(PATCHLEVEL).$(SUBLEVEL)$(EXTRAVERSION)
exceeds 64 characters it silently corrupts the utsname data, resulting
in garbage for uname -r and problems running the kernel and modules.
Abort if KERNELRELEASE is too long. Truncation is not good enough, it
results in ambiguous /lib/modules/`uname -r` contents.
Ensure that the date/time in uname are always in LANG=C. Users with
other languages report that 8 bit values cause the boot messages to go
haywire.
Both are backports from kbuild 2.5.
