Subject: Running make install over sshfs is painful now

Hi,

With the following commit running "make modules_install install" over
sshfs (and I suppose nfs) is extremely painful:

    kbuild: Fix checking of scm-identifier variable

    I'm looking Makefile in the -mm branch (dated 2010-04-28-16-53) and
    seeing what looks like a bug in the checking of scm-identifier.  The
    "ifneq ($scm-identifier)" seems to always execute "ifeq
    ($(LOCALVERSION,)) ...".  This patch fixes the checking of
    scm-identifier.

I compile my kernel on my workstation and then mount working tree over
sshfs and install on my laptop over wireless. It worked well for the
last few years but the latest changeset slows this process down to a
crawl - traversing git repository over the network is not the fastest
process out there. Any cfhance we could generate the tag at compile time
as opposed to install time?

Thanks.
