Subject: [libgfortran,patch] Build libgfortran when dup() and access() are not available

This patch provides a fallback implementation of acces(), using open (), that covers the cases used in io/unix.c. For dup(), the graceful degradation is probably the best we can provide, and should only fail when closing pre-connected units. (But then, for embedded targets, I'd say: so be it.)

Manually testeed on x86_64-linux, OK to commit?
