"libiconv" package doesn't build under Solaris

[Matthias Scheler <tron%zhadum.org.uk@localhost>]

        Hello,

after working around the bison issue(*) I'm stuck with another
Solaris/pkgsrc problem. The "libiconv" package fails to build:

if test -n "yes"; then  /bin/sh ../libtool --mode=link gcc -Wl,-R/opt/pkg/lib  
-I. -I. -I../include -I./../include -I.. -I./.. -O  -DLIBDIR=\"/opt/pkg/lib\"

-DINSTALLDIR=\"/opt/pkg/lib\" -DNO_XMALLOC  
-Dset_relocation_prefix=libiconv_set_relocation_prefix  
-Drelocate=libiconv_relocate -DHAVE_CONFIG_H -fPIC -DPIC -DLIBICONV_PLUG 
./iconv.c ./../libcharset/lib/localcharset.c ./relocatable.c -shared -o 
preloadable_libiconv_solaris.so;  else  /bin/sh ../libtool --mode=link gcc

It looks like "libtool" thinks that it is linking a program and not
a shared object. I've tried to replace "-shared" with "-module" but
it doesn't help. Any ideas how to fix that?

        Kind regards
