[Ur] problems building Ur/Web on OS X since the change to dynamic so libs

[Georg Bauer]

Hi,

since the change to dynamically loaded liburweb about 3 weeks ago,
there is a problem with building on OS X: (only noticed it today when
trying to build the new version)

gcc -shared -Wl,-soname,liburweb.so.1 -o lib/c/liburweb.so.1.0
lib/c/memmem.do lib/c/urweb.do lib/c/queue.do lib/c/request.do
lib/c/mhash.do
ld: unknown option: -soname
collect2: ld returned 1 exit status

The relevant change is

Makefile.in @ 1095:bed675db3aff

OS X doesn't have a -soname parameter due to the different form of
dynamic libs (they are dylib bundles there, not so files). No idea if
anyone has a patch to fix that, but for now it doesn't build on OS X
(before it did compile and run just fine).

bye, Georg
