BUG#: 7514
TITLE: Allow Linux build to use default include and library paths for ICU components

DESCRIPTION: Modified code to (1) Allow the use of the PEGASUS_HAS_ICU variable to trigger in inclusion of ICU in the build (2) If ICU_INSTALL or ICU_ROOT are not set, the build will assume that the ICU libraries and include files are in the default search path (3) To improve readability, removed the nested if statements used to define the link command for the PEGASUS_PLATFORM_LINUX_GENERIC_GNU platforms.
