If it's a "real" stub (ie, one in the spec file), then the app won't
correctly run under Wine, since when it'll call that stub it'll crash
with a SIGSEGV (0xdeadbeef et al). Not sure if allowing them to link
under winelib is correct here.

For the other type (one labeled stub in the C files, which just print
some TRACES), it's a real function, so nothing needs to be done.

Make a program (winebuild called) which checks for functions ld can't
find, and create a corresponding stub in an additional source file.
Problem is, you need the prototype for that, and since the prototypes
are in the spec files, and for stubs the prototype is absent, you have a
nice round problem.

If implementing the real stubs to return error codes can make the app
work under Wine, then you've just solved your problem.
