Fix loder(1) to work with libraries. This can be useful to
sort long DPADD lists automatically. While here, recognize
`W' as the global symbol. This has been tested since 2004.

Give the -o option before any filename operands when invoking the sort
utility. 1003.1-2001 does not allow sort to accept the -o option after
the operands (Base Definitions, 12.2 Utility Syntax Guidelines,
Guideline 9).

Make it work with POSIX sort (POS arg)
All old sorts understand -k too.

Pick up the environment variable ${NM} if it exists and use that to list
symbols. This allows lorder to be used more easily in a cross-build
environment.

Use different filenames.

Removed explict PATH which tended to cause the *wrong* path to be used
more often than not.

Also included Doug Rabson's changes to make this script better handle the
two varieties of nm output we now have.

This commit was generated by cvs2svn to compensate for changes in r1590,
which included commits to RCS files with non-trunk default branches.
