[Qt-interest] [PATCH 2/2] mkspecs/qws: Use $(CROSS_COMPILE) to set the gcc prefix

[Grant Likely]

$(CROSS_COMPILE) is commonly used to set the gcc prefix when
cross compiling.  This patch enables the qws generic target to
pick up the correct cross compiler at configure time without
modifying/adding config files.

Using CROSS_COMPILE also eliminates the need for the qt config
files to know about all the possible gcc cross compiler
configurations.  For example, ELDK uses a different prefix for
each target.  On PowerPC alone ELDK provides ppc_4xx-gcc,
ppc_4xxFP-gcc, ppc_6xx-gcc, ppc_7xx-gcc, ppc_8xx-gcc, ppc_74xx-gcc,
ppc_82xx-gcc, ppc_85xx-gcc, and ppc_85xxDP.
