Fix stlink on mingw64

[oli-obk]

%zx gets printed as zx. Just using %x suffices in the cases in this PR.

This fixes stlink for us.

Great, thanks for the improvement!

[xor-gate]

Sorry reverted in PR #573

[oli-obk]

Hmmm... That's unfortunate... Isn't there a platform independent formatting? We could cast it to something that works everywhere.
Also, why wasn't this caught by Travis?

[xor-gate]

yes, %zu is in the C99 standard. but .... mingw64 wraps windows printf which probably doesn't support it (or use %Ix "which is portable accoding to microsoft MSDN") :(

z Specifies that a following d, i, o, u, x, or X conversion specifier applies to a size_t 
or the corresponding signed integer type argument; or that a following n 
conversion specifier applies to a pointer to a signed integer type corresponding to size_t argument.

Would you accept a PR turning formatting warnings into errors on Travis and casting all size_t formatting to unsigned long long before formatting?

[xor-gate]

Sure, just make a proposal!
