libc/uclibc: use CT_ARCH, in place of CT_KERNEL_ARCH

Since we merged the 32/64-bit archs, and we explicitly used
the Linux kernel arch name, we can get rid of CT_KERNEL_ARCH.

    11       gcc is the full-blown GNU compiler. This is what most people will choose.

    12       

    13       gcc supports many languages, a powerful code parser, optimised binary

    14       output, and lots of other features.
