[PATCH] allow multiple debuginfo packages installed

[Aristeu Rozanski]

Currently it's not possible to install multiple debuginfo packages in
the same system. See:
	https://bugzilla.redhat.com/show_bug.cgi?id=435941
	(unfortunately only available for RH engineers)
This patch fixes the problem by simply changing the directory name where
the kernel is built. Because normally the directory used will be
linux-2.6.35.x86_64, linux-2.6.35-1 and linux-2.6.35-2 won't be allowed
to co-exist because of file conflict.
