Log Message:
lang/gcc16: Guard Linux-only open(2) flags with #ifdef for NetBSD portability

Adds patch to libgcobol/posix/shim/open.cc to wrap O_DIRECT, O_LARGEFILE,
O_NOATIME, O_PATH and O_TMPFILE in #ifdef guards; these flags are
Linux-specific and not defined on NetBSD.

+Guard Linux-specific open(2) flags (O_DIRECT, O_LARGEFILE, O_NOATIME,
+O_PATH, O_TMPFILE) with #ifdef so libgcobol builds on NetBSD, where
+these flags are not defined.
