Description of problem:

I encountered the build error when try to build openais on IA64. The error is
caused by exec/keygen.c, line 75:

    authkey_fd = open ("/etc/ais/authkey", O_CREAT|O_WRONLY);

Adding the third argument could fix it.

    authkey_fd = open ("/etc/ais/authkey", O_CREAT|O_WRONLY,
S_IRUSR|S_IWUSR|S_IRGRP);

Version-Release number of selected component (if applicable):
openais-0.80.1-6.src.rpm

How reproducible:
always

Steps to Reproduce:
1. rpmbuild --rebuild openais-0.80.1-6.src.rpm
2.
3.
  
Actual results:

/usr/include/bits/fcntl2.h:51: error: call to '__open_missing_mode' declared
with attribute error: open with O_CREAT in second argument
needs 3 arguments                                                              
                                                         
make[1]: *** [keygen.o] Error 1

Expected results:

Build cleanly
