Winebuild : Ignore if nm return no symbol error

[Pierre d'Herbemont]

Hi,
If I build d3dim for example on Mac OS X, I get an error fom winebuild 
saying that there is no symbol to list, and the result of this is an 
error (code 0x100). This patch prevent winebuild from throwing an error.

Thanks ;)

Pierre

ChangeLog:
- no fatal error if nm doesn't have any symbol to list.
