This change is not working for me on Ubuntu 11.04 {released}.
The libraries are found in /lib/i386-linux-gnu and /usr/lib/i386-linux-gnu
At least on the machine where it fails, uname -m gives i686, so the test
   >> ++test -f /usr/lib/`uname -m`-linux-gnu/libc.so&& glibpth="/usr/lib/`uname -m`-linux-gnu $glibpth"
fails.

I hard coded the i386-linux-gnu paths and was able to build perl-native on Ubuntu 11.04
