[PATCH] kbuild: Eliminate build error when KALLSYMS not defined

The following build error happens with 2.6.14-rc4 when CONFIG_KALLSYMS is
not defined.  The error message in a fragment of the output was:

  CC      arch/i386/lib/usercopy.o
  AR      arch/i386/lib/lib.a
/bin/sh: line 1: +@: command not found
make[3]: warning: jobserver unavailable: using -j1.  Add `+' to parent make rule.
  CHK     include/linux/compile.h
