    x86_64: Remove unneeded static PIE check for undefined weak diagnostic

    https://sourceware.org/bugzilla/show_bug.cgi?id=21782 dropped an ld
    diagnostic for R_X86_64_PC32 referencing an undefined weak symbol in
    -pie links.  Arguably keeping the diagnostic like other ports is more
    correct, since statically resolving movl foo(%rip), %eax to the
    link-time zero address produces a corrupted output.

    It turns out that --enable-static-pie builds do not depend on the ld
    behavior. GCC generates GOT indirection for weak declarations for
    -fPIE/-fPIC, so what ld does with the PC-relative relocation doesn't
    really matter.
