[Patch 1/1] BaseTools: Fixed an issue that build raise exception

["Bob Feng" <bob.c.feng@intel.com>]

BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=2047

Build raise exception if there is libraryclass
missing in dsc file and --pcd build option is used.

Build should report the missing libraryclass but not
a call stack.

This patch is going to fix it.
