Okay.

Randconfig testing found another corner case with the attached config:

    KSYMS   .tmp_vmlinux0.kallsyms.S
    AS      .tmp_vmlinux0.kallsyms.o
    LD      .tmp_vmlinux1
  ld: percpu cache hot section too large
  make[2]: *** [scripts/Makefile.vmlinux:77: vmlinux] Error 1

(I haven't figured out the root cause yet.)
