That's good. CMake might do the following (in a simplistic way):

# find the regular gcc (do as CMakeDetermineCCompiler.cmake does, tough)
find_program(CC_BASIC gcc)

# Discover the machine this gcc generates code to
execute_process(COMMAND ${CC_BASIC} -dumpmachine OUTPUT_VARIABLE MACHINE)

# Find a properly named gcc
find_program(CC_COMPLETE ${MACHINE}-gcc)

# Set CC to the above compiler if it exists.
if(CC_COMPLETE)
	set(CC ${CC_COMPLETE})
else(CC_COMPLETE)
	set(CC ${CC_BASIC})
endif(CC_COMPLETE)

Anyone agrees?
