Issue with $(location) on macOS

This target fails to build on macOS (Apple Silicon):

genrule(
    name = "hello",
    srcs = ["@ape//ape:echo"],
    outs = ["echo.out"],
    cmd = "$(location @ape//ape:echo) world > $@",
)

With this error:

ERROR: /Users/aleter01/Sandbox/ape-bug/BUILD.bazel:1:8: in cmd attribute of genrule rule //:hello: label '@@ape+//ape:echo' in $(location) expression expands to more than one file, please use $(locations @@ape+//ape:echo) instead.
