The root cause of https://golang.org/issue/16780 is that GCC on s390
GNU/Linux does not emit a .file directive.  This is because the
function s390_asm_file_start does not call default_file_start, unlike
most other TARGET_ASM_FILE_START hooks.  This patch should fix the
problem.  Since I don't have an s390 handy, it would be great if
somebody could test this for me.  Thanks.

Ian
