The solution is to add the --disable-dependency-tracking option to the
configure command as follows:

./configure CC='/usr/bin/gcc-4.0' CPP='/usr/bin/cpp-4.0'
CXX='/usr/bin/g++-4.0' CXXCPP='/usr/bin/cpp-4.0' CFLAGS='-arch i386 -arch
x86_64' CPPFLAGS='-arch i386 -arch x86_64' CXXFLAGS='-arch i386 -arch
x86_64' LDFLAGS='-arch i386 -arch x86_64' --disable-dependency-tracking

$ make -j 6
$ sudo make install
$ cd ../

$ file /usr/local/lib/libltdl.dylib

/usr/local/lib/libltdl.dylib: Mach-O universal binary with 2 architectures
/usr/local/lib/libltdl.dylib (for architecture i386):   Mach-O dynamically
linked shared library i386
/usr/local/lib/libltdl.dylib (for architecture x86_64): Mach-O 64-bit
dynamically linked shared library x86_64
