When running tests on OpenRISC which has 32-bit wordsize but 64-bit timesize it was found that O_LARGEFILE is not being set when calling open64. For 64-bit architectures the O_LARGEFILE flag is generally implied by the kernel according to force_o_largefile. However, for 32-bit architectures this is not done. For this patch we unconditionally now set the O_LARGEFILE flag for open64 class syscalls as there is no harm in doing so. Tested on the OpenRISC the build works and timezone/tst-tzset passes which was failing before. I would expect this also would fix arc. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
