icecc: Support shell evaluation of KERNEL_CC
In the current implementation a KERNEL_CC variable containing shell evaluation breaks the build process. Shell expansion is not happening before general expansion in get_cross_kernel_cc which results in a syntax error and an aborted parse process. Before expanding the KERNEL_CC variable get_cross_kernel_cc now checks for backticks or '$(' in the KERNEL_CC variable and performs a shell evaluation using a call to echo if it finds one.
