Prior to commit 5d45950dfbb1 ("kbuild: move vmlinux.o link to
scripts/Makefile.vmlinux_o"), jobserver-exec was invoked from the shell
script, link-vmlinux.sh. It can get access to the jobserver because
Makefile adds '+' prefix, as in:
+$(call if_changed_dep,link_vmlinux)
Since 5d45950dfbb1, jobserver-exec is invoked from Makefile, but the
'+' prefix is missing, hence jobserver-exec has no access to the
jobserver.
Fixes: 5d45950dfbb1 ("kbuild: move vmlinux.o link to scripts/Makefile.vmlinux_o")
