executor: undefined reference to `guest_uexit' #6999
Description
Describe the bug
Syzkaller over the last few weeks does not build on amd64 - builds work on arm64
To Reproduce
export HOSTARCH=amd64
export GOARCH=amd64
cd syzkaller && make HOSTARCH=$(HOSTARCH) TARGETARCH=$(GOARCH)
Expected behavior
Build completes
