I was searching for Small-C information (it seems that cc65 is descended from Small-C) and found this:

a version of small-c for the 6502 and LUnix [by] Ivan A. Curtis
Quote:
scc6502, a version of the small-c compiler for the 6502, specifically designed for the C-64 running the LUnix operating system. Changes to the assembly syntax and the runtime will allow it to be used for other 6502 systems.


From the included SCC_README file:
Quote:
Small C version C3.0R1.1 (SCC3) [by] Chris Lewis

This directory contains the source for a version of Ron Cain's Small C
compiler that I have heavily modified - beyond the Small-C V2.0 later
published in Dr. Dobbs. This compiler generates assembler source code that
needs to be assembled and linked to make a running program.


In a similar vein, see also this $30 CD of info from Dr Dobbs:
Quote:
The CD-ROM includes James Hendrix's out-of-print book, A Small-C Compiler: Language, Usage, Theory, and Design, and several relevant articles from Dr. Dobb's Journal written by C experts such as Allen Holub.


Tangentially relevant, there's a doc by Edmund Grimley-Evans describing the bootstrapping of a C compiler, albeit on x86 and assuming ELF format executables:
Quote:
Bootstrapping a simple compiler from nothing
============================================

This document describes how I implemented a tiny compiler for a toy
programming language somewhat reminiscent of C and Forth. The funny
bit is that I implemented the compiler in the language itself without
directly using any previously existing software. So I started by
writing raw machine code in hexadecimal and then, through a series of
bootstrapping steps, gradually made programming easier for myself
while implementing better and better "languages".
Seen also on github (uploaded by Scott Taylor)

More bootstrapping references in this discussion.
