This question follows on from Can you tell me what "crus" means in "LDFLAGS = crus $@"?
Since my error message is "aarch64-poky-linux-ld: cannot find crus: No such file or directory", where can I find documentation on aarch64-poky-linux-ld?
Best regards,

All Linux systems I know of use GNU ld as their linker, part of the binutils package, and it has a complete manual. The aarch64-poky-linux- prefix is a target triplet, used to identify which cross-compilation target this particular ld executable is for.
However, all I think it will tell you is that a string which is not part of an option (starting with - or --) will be treated as an input file. So the message just reports that it is trying to use crus as an input file but it doesn't exist. That's not surprising because as was pointed out on your other question, crus appears to be meant as options to the ar program, not for ld at all. They don't make sense in an LDFLAGS variable. So you will need instead to debug whatever makefile or script decided to try to pass those "options" to aarch64-poky-linux-ld in the first place.
