icecc.bbclass: prevent nativesdk builds depending on target specific KERNEL_CC 

* without this we cause nativesdk-linux-libc-headers to depend
  on target specific KERNEL_CC (through icecc_get_tool ->
  icecc_is_kernel -> KERNEL_CC -> HOST_CC_KERNEL_ARCH ->
  TARGET_CC_KERNEL_ARCH -> TUNE_FEATURES(thumb) as shown by
  bitbake-diffsigs:
