[LINUX][PATCH] mMosaic needs additional lib

[Dario Niedermann <dnied%tiscali.it@localhost>]

As per GNU ld suggestion upon failure, libdl is needed on Linux in
order to build www/mMosaic-3.7.2nb11. So the '-ldl' option needs to be
specified on cc's command line. The attached patch takes care of that.

According to mMosaic's own Makefile, the same is needed for: HP-UX,
BSD/386, FreeBSD, Solaris 2.x, only to mention OSes supported by pkgsrc.
But I don't know how up-to-date that info is, and I don't have those
systems to test on, so I only introduced the change for Linux.
