linux26: do not set CFLAGS_KERNEL to TARGET_CFLAGS

Using TARGET_CFLAGS breaks the kernel build for the arm platform. The
result is a kernel that can not be booted. So simply do not fiddle with
the CFLAGS on a kernel build and the kernel build system will do the
right thing (TM).

[Peter: do the same thing for the standard kernel build]
