buildgcc: Add check for missing libraries and test for zlib

- Add check_for_library routine to test for missing libraries.
- Add a check for zlib.
- Remove 'utility' text from please_install() routine since we can test
for libraries or utilities now.
- Remove incorrect 'solution' text from alternate install since I was
updating that line.
