r313494 make perl File::Temp broken

Hi,

as not a perl programmer myself. I have no idea what is going on.
I found this issue while compiling math/openblas.

[iblis_at_ns]% uname -a
FreeBSD ns 12.0-CURRENT FreeBSD 12.0-CURRENT #1 r313500: Fri Feb 10 16:39:21 
CST 2017     root_at_ns:/usr/obj/usr/src/sys/GENERIC  amd64

[iblis_at_ns]% cat test.pl 
use File::Temp qw(tempfile);
$tmpf = new File::Temp( UNLINK => 1 );

[iblis_at_ns]% perl test.pl
Error in tempfile() using template /tmp/XXXXXXXXXX: Could not create temp file
/tmp/dI5uhUsijR: Bad file descriptor at test.pl line 2.


And part of truss's output:
