kernel: update build-kernel.sh script for x86
This updates the build-kernel.sh script to be able to rebuild
the x86 goldfish kernel from sources using our NDK-compatible
toolchain. This is needed because the toolchain is configured
with -mfpmath=sse and -fpic by default, which we need to disable.
Because the kernel build system doesn't allow us to provide extra
compiler flags easily, we create a "magic" wrapper toolchain to
do it for us (see toolbox.sh)
