I'm trying to build dtc on Mac OS X.  The compilation seems to go
okay, but the linker dies.

It doesn't die, it just complains ;-)

You're trying to build a Linux shared library on OSX.  This won't
work.  Not only are the command line options not the same, the
semantics are totally different as well; importantly, the versioning
mechanism is very different.  Given that, you do not want to use
a shared library at all -- just use a normal (static) library.
IMNSHO that should be the default, on Linux as well...
