Unfortuantely, this patch fails to bootstrap on linaro CI, but it bootstraps
fine on my machine. All my attempts to reproduce this failed, and I am really
not sure what to do from here.

https://patchwork.sourceware.org/project/gcc/patch/20240512133857.1634-1-peter0x44@disroot.org/

I won't be able to do any more without help.

This might arguably actually be a BFD linker problem. Both lld and mold don't
have the problem for the example. Gold also has the same issue.

I think this should be transferred over to binutils, since I was told my patch
in the driver wasn't desired anyway, and the specific issue doesn't show up
when using other linkers. Whether it's worth doing something for the cases of
`gcc -c file1.c -o file2.c` or others with -S and -E is a different issue, and
a separate bug should be filed for that, if it's desired to do anything.

I am no longer working on this.
