[PATCH] Bug 16442 - Missing futimes() on Solaris

[Игорь Пашев]

http://llvm.org/bugs/show_bug.cgi?id=16442

Solaris does not provide futimes(), OS X does not have futimens().
futimens() is POSIX.1-2008 standard, futimes() is a BSD extension.
glibc-based systems have both, illumos has futimens().

autotools files should be regenerated.
