[Tizen] Use -mstackrealign to sync up with Tizen build changes

Tizen i586 now builds with -mstackrealign by default:

    "Realign the stack at entry. On the x86, the -mstackrealign option
    generates an alternate prologue and epilogue that realigns the
    run-time stack if necessary. This supports mixing legacy codes that
    keep 4-byte stack alignment with modern codes that keep 16-byte
    stack alignment for SSE compatibility. ..."
