    libiberty/mkstemps.c: Include <time.h> if <sys/time.h> not available.
    
    Attempting to build libiberty on LynxOS-178 fails trying to compile
    mkstemps.c with the following error:
    
        mkstemps.c:84:18: error: storage size of 'tv' isn't known
           struct timeval tv;
                          ^
    
    This file would normally include <sys/time.h> to get the type's
    definition, but unfortunately LynxOS-178 does not want us to use
    <sys/time.h>, only <time.h>. The configure script correctly finds
    this out and generates a config.h file where HAVE_SYS_TIME_H is
    undefined:
    
    /* Define to 1 if you have the <sys/time.h> header file. */
    /* #undef HAVE_SYS_TIME_H */
    
    This patch fixes the build issue by falling back on including <time.h>
    if <sys/time.h> could not be included (and provided that HAVE_TIME_H
    is defined, of course).
    
    libiberty/ChangeLog:
    
            * mkstemps.c: #include <time.h> if HAVE_TIME_H is defined
            but not HAVE_SYS_TIME_H.
