kbuild: add symbol prefix arg to kallsyms
Commit 1f2bfbd00e466ff3489b2ca5cc75b1cccd14c123 ("kbuild: link of vmlinux moved to a script") introduced in v3.5-rc1 broke kallsyms on architectures which have symbol prefixes. The --symbol-prefix argument used to be added to the KALLSYMS command line from the architecture Makefile, however this isn't picked up by the new scripts/link-vmlinux.sh. This resulted in symbols like kallsyms_addresses being added which weren't correctly overriding the weak symbols such as _kallsyms_addresses. These could then trigger BUG_ONs in kallsyms code. This is fixed by removing the KALLSYMS addition from the architecture Makefile, and using CONFIG_SYMBOL_PREFIX in the link-vmlinux.sh script to determine whether to add the --symbol-prefix argument.
