[PATCH v2] x86: Check invalid GOT/PLT/TLS relocations

1. Since non-alloc sections aren't checked for TLS, GOT and PLT usages,
relocate_section should issue error for TLS, GOT and PLT relocations in
non-alloc and non-debugging sections.
2. Since TLS relocations must be against thread local symbols, scan_relocs
should issue an error for TLS relocation against non-thread local symbol.
