The ELF generator is quite complicated, so I am relunctant to begin a
a.out generator. A closely related issue is that a PE COFF generator
is also needed for a Windows version of TCC. I see the following

1) Use an ELF to a.out or ELF to PE COFF converter (objcopy ?).

2) Add BFD support in TCC for non ELF binary support.

3) Code a.out and PE COFF, if someone has the time to do it...
