build system: Eliminate special case for c_start

c_start.o has a special case in the build system, which we can
eliminate, somewhat simplifying the build.

To ensure that the entry point is at the beginning, introduce a
new section .textfirst that is placed appropriately. In principle
the ENTRY() definition in the linker script should be enough, but
better be safe.
