Hi,
Here's what I was running into during an install of Freescale's latest BSP
L3.0.35_4.0.0_130424_source.tar.gz on Ubuntu 12.04
In Ubuntu 12.04 the location of zlib moved, but zlib-devel did not.
zlib has two matches for libz.so* (file and symlink) and zlib-devel adds
another (file).
Both zlib and zlib-devel are required packages as defined in ./ltib's list.
My initial thought was that it only needs one library to link against e.g.
zlib-devel.
But I guess I don't know that for sure.
If all are required maybe ltib should check for 3.
Anyway, I added the path instead of changing the file count limit.

Subject: [PATCH 1/5] ltib add path to libz check on ubuntu 12.04
Added path to ltib installation check for the presence of libz.
ltib checks for libz installation by looking for libz.so* in a hard
coded list of the paths. If there are two or more listings (one
for the lib and one for the real name and one for the fully-qualified
soname) the check is satisfied.
Everytime the path for libz moves in a new host linux distribution
this list of paths needs updated.

Hi Mike,
I can't remember whether or not that was deliberate. I think it was.
The idea is that it's looking for a symlink and the file it points to,
so there should be 2 (at least).
