[PATCH] makedep: Support using MSVC-style delayload linking.

[Jacek Caban]

llvm-dlltool doesn't support support delay import lib, but we don't need 
them if linker itself supports delayload. lld-link supports it, so use 
it when possible.

With this patch, it's possible to do 64-bit build with llvm-mingw [1]. 
No extra config arguments are needed. 32-bit builds need a bit more 
fixes. Also, it won't work yet, mostly because export tables are broken. 
I have patches for that.
