List of target formats supported by gcc and ld

It's been more than a while I've been googling on this topic. Few years back, I came across a page which listed all the target formats and target machines supported by both gcc and ld. But recently, that page seems to go out of existence. I even tried checking gcc manual and configure options. It seems they have skipped this part altogether.
If anyone have a link that I may find useful, please post in.
Edit: I seem to recall that ld had a switch that enlists object file formats it is configured to support. Well, I can't remember the exact switch so if anyone knows, that too would be very helpful.

Not even 1% of all object formats supported by ld.

It's easy to skip over what's been compiled in:
Code: Select all
$ x86_64-pe-ld --help
(...)
x86_64-pe-ld: supported targets: pe-x86-64 pei-x86-64 pe-bigobj-x86-64 elf64-x86-64 elf64-l1om elf64-k1om pe-i386 pei-i386 elf32-i386 elf64-little elf64-big elf32-little elf32-big plugin srec symbolsrec verilog tekhex binary ihex
x86_64-pe-ld: supported emulations: i386pep i386pe
(...)
As to what it
could support, assume everything that's not 16-bit or a trade secret of sorts.

Great!

For my ELLCC clang based cross development tool project, I build ld to support quite a variety of targets. ld --help:
