We need to determine that the variable is a "tls" variable. When this is
extern, the symbol is LOC_UNRESOLVED. So the section type from "sym" is
not filled. Thats why I tried to determine this from the minimal symbol.
If there is any other method of determining a variable is "tls" before
its owning symtab is linked in, could you please inform? I used this
section number as I could not find another way of determining this..
