Fix configure to work with Solaris Studio compilers
Passing -Werror in the scandir() checks caused Studio cc to report
"Unrecognized option errors", confusing configure into thinking that
scandir() was not available. Use Studio equivalent flags instead.
Leaves -Werror as the default for all other compilers, including
unknown ones, to flag to them that they need to update their flags
as well if -Werror is not correct for them.
