CONFIG_KPROBES=y build requires gawk

[Andrew Isaacson <adi@vmware.com>]

With CONFIG_KPROBES=y on Ubuntu 9.10 x86_64 default install, I get the
following:

Error: Your awk doesn't support charactor-class.
Please try to use gawk.
  CC      arch/x86/lib/inat.o

make: *** [arch/x86/lib] Error 2

Either CONFIG_KPROBES=n or 'apt-get install gawk' does the trick, but is
this intentional?

If it is, the following documentation patch should be applied.
