I cannot reproduce this. Your config file looks sane as far as the
kernel settings are concerned.
I just modified the path to the kernel and patch directory, then I get:

$ make linux-dirclean
rm -Rf /tmp/buildroot-2013.08/output/build/linux-custom
tdescham at argentina /tmp/buildroot-2013.08 $ make linux-patch
>>> linux custom Download additional patches
>>> linux custom Extracting
bzcat /tmp/buildroot-2013.08/dl/linux-3.9.4.tar.bz2 | tar
--strip-components=1 -C
/tmp/buildroot-2013.08/output/build/linux-custom  -xf -
>>> linux custom Patching /package/linux
for p in /tmp/foo ; do if echo $p | grep -q -E "^ftp://|^http://" ;
then support/scripts/apply-patches.sh
/tmp/buildroot-2013.08/dl `basename $p` ; elif test -d $p ; then
/tmp/buildroot-2013.08/output/build/linux-custom $p linux-\*.patch ;
else support/scripts/apply-patches.sh
/tmp/buildroot-2013.08/output/build/linux-custom `dirname $p`
`basename $p` ; fi done

Applying linux-bar.patch using patch:

The corresponding settings were:

Your config file indicates that this is not a clean buildroot tree.
Have you verified this issue on a clean buildroot-2013.08 release?
Were any changes made in this area?

If the problem is still present, you could instrument linux/linux.mk
with some echo statements, particularly in the LINUX_DOWNLOAD_PATCHES

Best regards,
