Sort of. You don't need a separate build tree for building the tests. Just have mingw32 installed, run ./configure, then 'make crosstest'.
I've done 'make crosstest' many times, but building winetest.exe itself does seem to require the two trees as described by that page.
For that one can also look at testbot/bin/buil/Reconfig.pl, specifically BuildNative() and BuildCross() (in the tools repository).
(But as it turns out, the code I needed to fix was in buildbot, not winetest.)
Maybe the WineTestBot code needs a similar fix? In testbot/src/TestLauncher/TestLauncher.c?
