Hello Sam,
I use parallels, a hypervisor based virtual machine, for Linux which
ships with binary kernel modules and a bit of gluecode. After your
commit 20a468b51325b3636785a8ca0047ae514b39cbd5 in the linux kernel the
compilation of this kernel modules ends up in an endless-loop. I don't
think that this is a problem of the kernel build system but the way
paralles does abuse the kernel build system (they use autoconf to
generate a makefile which looks obvious broken). However I tracked the
offending delta down to the following:
(mini) [~/work/linux-2.6] git diff -R
diff --git a/scripts/Makefile.build b/scripts/Makefile.build
index acd3b96..e48e60d 100644
--- a/scripts/Makefile.build
+++ b/scripts/Makefile.build
@@ -10,11 +10,12 @@ __build:

If you reverse apply this delta of your patch, it works again. I don't
get what is going wrong here, but maybe you want to have a look at it.
To reproduce:
* Go to http://www.parallels.com/en/download/ and download the packages for your distribution
cd /usr/lib/parallels
./configure
make
if you do this with a recent kernel version (newer than
20a468b51325b3636785a8ca0047ae514b39cbd5) it ends in an endless-loop
otherwise it works.
The broken parallels makefiles are in:
/usr/lib/parallels/drivers/drv_net/linux/Makefile
/usr/lib/parallels/drivers/drv_net/Makefile
/usr/lib/parallels/drivers/drv_virtualnic/Makefile
/usr/lib/parallels/drivers/drv_main/Makefile
/usr/lib/parallels/drivers/hypervisor/Makefile <<<<< This is the first one which breaks. The other follow.
/usr/lib/parallels/drivers/Makefile
I also created a website for my findings: http://thomas.glanzmann.de/parallels/
