selftests/nolibc: always compile the kernel with GCC

Browse Source 
LLVM/clang can not build the kernel for all architectures supported by
nolibc. The current setup uses the same compiler to build the kernel as
is used for nolibc-test. This prevents using the full qemu-system tests
for LLVM builds.

Instead always build the kernel with GCC. For the nolibc testsuite the
kernel does not need to be built with LLVM.
