The command length of in-target scales with the depth of the directory times the number of objects in the Makefile. When there are many objects, and O=[absolute_path] is set, and the absolute_path is relatively long. It is possible that this line "$(call if_changed,$(host)ld_multi)" will report error: "make[4]: /bin/sh: Argument list too long" For example, build perf tools with O=/long/output/path Like built-in.a and *.mod rules in scripts/Makefile.build, add $(objpredix)/ by the shell command instead of by Make's builtin function.
