--as-needed ld option

[Georg Schwarz <georg.schwarz%freenet.de@localhost>]

When compiling sysutils/eggdbus on MacOS 10.6.4 I end up like this:

libtool: link: gcc -D_EGG_DBUS_COMPILATION -D_REENTRANT

I found this web page about --as-needed:

http://www.gentoo.org/proj/en/qa/asneeded.xml

When I manually eliminated the respective line in configure.ac this worked fine.
Is this an issue on systems (using gcc) other than MacOS X, too?

What would be the appropriate solution? To patch some extra condition into 
configure.ac? To have buildlink eliminate that option?
