Tru64/OSF cc and -input

[Ralf Wildenhues]

On Tru64/OSF and with cc, $archive_expsym_cmds uses $LD and -input
in branch-1-5.  On HEAD, we switched to using $CC for linking, but
cc does not understand -input right:

| libtool: link:  cc -shared -input .libs/libfoo2.so.0.0.0.exp     .libs/foo2.o
| -lm ./.libs/libsub.so -soname libfoo2.so.0 `test -n "0.0.0:0.0" && print -r 
"X-set_version 0.0.0:0.0" | /bin/sed -e 1s/^X//` -update_registry 
.libs/so_locations -o .libs/libfoo2.so.0.0.0
| ld:
| can't open input file '-soname'(No such file or directory)

The documentation I have lists -input_to_ld as equivalent, but I don't
see why we shouldn't just use `-Wl,-input -Wl,$lib.exp' like we do for
cxx.

So I'm applying the patch below.  It fixes mdemo-make after mdemo-conf
and mdemo-shared, as well as mdemo-dryrun test failures on OSF 4.0D.

Cheers,
Ralf

        <archive_expsym_cmds>: Use `${wl}-input' not `-input', for
        cc.  Could use `-input_to_ld'.
        (_LT_LANG_CXX_CONFIG) [ osf4, osf5 ] <archive_expsym_cmds>:
        Use `${wl}' instead of `-Wl,', for consistency.
