binutils-2.15.92.0.2 -M script truncates file names

[Joe Buehler]

I had some problems building VirtualBox on a RedHat 3 ES machine,
The "ar" command failed to find an input file -- the message shows a
truncated
name compared to what is in the script fed in via -M.

Looking at the source code it appears that the grammar file that
specifies the
allowable characters in file names in -M script files is far too
restrictive.
In my case, I was running in an AFS file system and there was an @ in
the path name -- that is not allowd by the grammar.

The grammar needs to be fixed to not be so restrictive on what is allowed
in file names.
