Error in compiling uClibc

How do I fix it?

I think that something needs to be corrected here.

cat .config

KERNEL_HEADERS="/usr/include"
HAVE_DOT_CONFIG=y

This is the listing of the directory /usr/src

# ls /usr/src/
fglrx-8.960      linux-2.6.35.13.tar.bz2  linux-headers-3.2.0-23-generic
linux-headers-3.2.0-25-generic
linux-2.6.35.13  linux-headers-3.2.0-23   linux-headers-3.2.0-25
