--- Comment #2 from H.J. Lu <hjl.tools at gmail dot com> ---
Does -fno-common fix the problem?  If it is the case, we need to
treat common symbol differently for ia64 since

    .common    b#,8,4
    .common    a#,4,4

won't be placed in small data section reachable via GP reloc. The
problem for ia64 is even if a data symbol is defined locally, we
can't use GP reloc if it isn't placed in small data section.
