[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.
