That also is a combination that exhibits the problem as amd64 compiler
flags include -fcf-protection=full, which an arm64 compiler does not
understand. I call this build=arm64, host=amd64 (and in case of gcc-avr
always target=avr). Given your earlier mails, I think that the reverse
direction where build=amd64 and host=arm64 is much faster for you and
also exhibits the problem as -mbranch-protection=standard is an arm64
compiler flag that the amd64 compiler does not understand.
