buildgcc: Define $CMAKE only if clang package is built

This moves the CMAKE definition down into the case statement
for $PACKAGE so that it is only required when the user wants to
build clang.

With this approach, "./buildgcc -P clang" will error out with the
"ERROR: Missing tool:" message if cmake is not installed.
