Make a 16-bit test in wine for krnl386.exe16

[Bruno Jesus]

Hi all, I'm trying to create tests for GetPrivateProfileString16 but
it is not working as expected because the test is calling the kernel32
version of the function instead of the krnl386.exe16.

Is there any way to make a test that compiles and runs against krnl386
instead of kernel32?

I tried a few different things and the attached patch is the last
attempt (the tests are wrong but that is not the point yet).

Any help is appreciated, thanks in advance,
Bruno
