Move the calculation of the entry point to after the description
of the .text section. LOADADDR(.text) is not available earlier
with lld.
With this, lld builds working kernels on i386.
Also: Should this be __start_phys? It seems odd that we put a
non-reserved symbol into the kernel namespace. start_phys is not
referenced anywhere by the kernel code and this is the only place
it appears in the source tree.
