Options for 64 bit missing in linkmode during symbol table compilation

[Dagobert Michelsen]

Hi,

I have a problem mit the current libtool provided by OpenLDAP 2.4.17  
when
linking 64 bit. Obviously, the flags to turn on 64 bit compilation are
not passed (-xarch=v9 or -m64)

This is what the call looks like:

Executing libtool with -x reveals the wrong compiler call:

> + pic_flag_for_symtable=
> + echo '(cd .libs && /opt/studio/SOS11/SUNWspro/bin/cc   -c  
> "slapdS.c")'
> (cd .libs && /opt/studio/SOS11/SUNWspro/bin/cc   -c "slapdS.c")
> + eval '(cd $output_objdir && $LTCC  $LTCFLAGS -c$no_builtin_flag 
> $pic_flag_for_symtable "$dlsyms")'
> ++ cd .libs
> ++ /opt/studio/SOS11/SUNWspro/bin/cc -c slapdS.c
> + echo 'rm -f .libs/slapdS.c .libs/slapd.nm .libs/slapd.nmS .libs/ 
> slapd.nmT'
> rm -f .libs/slapdS.c .libs/slapd.nm .libs/slapd.nmS .libs/slapd.nmT
> + rm -f .libs/slapdS.c .libs/slapd.nm .libs/slapd.nmS .libs/slapd.nmT

Something like this seems to be needed, although I am pretty sure that  
I have
done it wrong:

It would be greate if you could do a permanent fix for this.
