Not a bad idea.

It was easy to track down since the linker was complaining about the object
format. Turns out nasm -hf tells you the default and possible values.
nasm -hf
usage: nasm [-@ response file] [-o outfile] [-f format] [-l listfile]
[options...] [--] filename
or nasm -v (or --v) for version info
...
valid output formats for -f are (`*' denotes default):
* bin flat-form binary files (e.g. DOS .COM, .SYS)
ith Intel hex
srec Motorola S-records
aout Linux a.out object files
aoutb NetBSD/FreeBSD a.out object files
coff COFF (i386) object files (e.g. DJGPP for DOS)
elf32 ELF32 (i386) object files (e.g. Linux)
elf64 ELF64 (x86_64) object files (e.g. Linux)
elfx32 ELFX32 (x86_64) object files (e.g. Linux)
as86 Linux as86 (bin86 version 0.3) object files
obj MS-DOS 16-bit/32-bit OMF object files
win32 Microsoft Win32 (i386) object files
win64 Microsoft Win64 (x86-64) object files
rdf Relocatable Dynamic Object File Format v2.0
ieee IEEE-695 (LADsoft variant) object file format
macho32 NeXTstep/OpenStep/Rhapsody/Darwin/MacOS X (i386) object files
macho64 NeXTstep/OpenStep/Rhapsody/Darwin/MacOS X (x86_64) object files
dbg Trace of all info passed to output stage
elf ELF (short name for ELF32)
macho MACHO (short name for MACHO32)
win WIN (short name for WIN32)
Thanks,
