It's hard to give advice without seeing what you have already.  How 
about showing us your .cygport files?

Unless you can $triplet-namespace the textdomain, you might just need to 
not package those.

Wouldn't this belong in /usr/$triplet/lib/?

That shouldn't be necessary.

Whatever you do, the cross-compilers need to match what the target's 
native compiler would do.  So if mingw's own toolchains are shipping and 
using shared GCC libraries, AFAICS you should do the same by enabling 
shared libraries and shipping the *import* libs but NOT the DLLs (which 
you only need to *execute* programs, which you're not doing because this 
is a *cross*-compile situation).
