Thanks for testing!

There were two typos in the --host branch of WINE_CHECK_HOST_TOOL(). 
First ${ac_tool_prefix} already contains the trailing dash so I should 
not have added one, but that hardly mattered since I had an extra 
"_tool" in the variable I was setting (a copy/paste error). The result 
of all that is that the macro was just returning the plain pkg-config 
tool in the end.

As far as I can tell the --host case now works as expected in the patch 
below.

    configure: Take the target host into account in WINE_CHECK_HOST_TOOL().
    
    In particular this gets us the right pkg-config tool when building the
    32 bit Wine.
