wscript: Allow start code to be written in C

Browse Source 
Start code for most platforms requires hand-coded ASM but some can be
bootstrapped entirely in C, especially for paravirtualized platforms.
This change allows start code to be written in C where possible instead
of requiring architecture-specific ASM to bridge to C.
