While the scan of src/cmd/als.s clearly refers to ferror,
that routine is entirely missing from the scans of ald.
There are two identical ferror routines in src/cmd/adm.s and
src/cmd/apr.s printing the file name of a file that cannot be
openend.
ald calls ferror when unable to create a file. For ald to have
a similar ferror routine when creation fails appears sensible.
Therefore a similar routine is added to src/cmd/ald.s with
modifications to the variable containing the file name and
the label ferror jumps back to once done.
