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.
