http://kernelnewbies.org is the community's "where do I start" website.  
They have mentoring programs that are likely to provide more attention  
than you'll get here.

2.6.11. Huh. Quarterly releases, 3.0 would have been 2.6.40, we're now  
up to 3.10, so 39 releases ago...

That's almost a decade old. No idea, it could be anything...

You didn't say which kernel version you were trying to build. If it's  
2.6.11, most of us aren't going to remember the details it was so long  
ago.

Sounds like your version of "make" is too old? The file  
Documentation/Changes in the kernel source lists the minimum tool  
versions, and I vaguely recall there was a make bug requiring a version  
upgrade in the past 10 years...

Yeah, 4 years ago:

commit 2185a5ecd98d2cebc6a29b07b1ea4f7334c2ccc3
Author: Adam Lackorzynski <adam@...inf.tu-dresden.de>
Date:   Sun Jun 14 22:38:59 2009 +0200

     documentation: make version fix

     The Makefiles in the build directories use the internal make  
variable
     MAKEFILE_LIST which is available from make 3.80 only.  (The patch  
would be
     valid back to 2.6.25)

Possibly the version of make in the 10 year old distro is too old?
