You can do a build on Solaris right before my changes, and see in what
section clz_table is.

Probably because the linker is only caring that clz_table is in the
TLS section when we try to use a relocation which is incompatible with
the usual kinds of linker relaxation relocation done on TLS symbols.

Normally the %tls_*() relocs are used with TLS symbols.

So we didn't properly mark object types, and the Solaris assembler
uses a terrible default for symbol types, adding up to symbols
inadvertantly ending up in the TLS section.
