Zld: Report archive file with cpu arch mismatch
This is just a simple/hacky feature to report the source of a linking error. I found this helpful in fixing-up some of my libs when recently switching from an x86_64 to aarch64 device, so thought it might be useful to others a well before zld has a fully featured error reporting system.
