Subject: [PATCH] setarch: prefer preprocessor rather than autotools check
05ad79
05ad79
It seems to be pointless to spend time in ./configure phase when
05ad79
preprocessor has to perform #ifndef check anyway.

[kzak@redhat.com: -
05ad79
   Note that on RHEL-7 glibc' <sys/personality.h> does not contain the
05ad79
   same set of the flags like <linux/personality.h>. We need to include
05ad79
   glibc version dues to syscall, so it seems better make our macro
05ad79
   fallbacks more robust.]
