Incorrect libtool built when cross compiling under Mac OSX

[Rudolf Leitgeb]

Dear Ladies and Gentlemen,

I may have triggered a bug in autoconf and would like to report  
details here.

I tried to build ImageMagick 6.4.7-4 in an Intel based iMac from  
sources. As long as
I compiled for i386 and x86_64, everything went fine, troubles  
started, when I tried
to cross compile for ppc and ppc64.

First I created a configure script with autoconf, with this configure  
script I
generated Makefiles and libtool, and this libtool does not work  
properly.

The following versions were used:

autoconf: 2.63
Mac OSX: 10.5.5
gcc toolchain: from xcode 3.1


Here's a description of my build problems. Note that these problems  
only appear
when I cross compile for ppc and ppc64!

configure looks for name lister tools, and tries two programs: dumpbin  
and link
I do have /bin/link, which is a hard link to /bin/ln, not a linker,  
but for
some reason configure doesn't discover that "/bin/link -dump -symbols"  
returns
an error.
For some unknown reason global_symbol_pipe remains empty, which  
ultimately
causes the make process to fail.

If I remove "link" from the list of programs configure tries to use as  
BSD name
lister, the build process works.

Please let me know if you need more information.

Cheers,

Rudi
