What exactly are you trying to do?  Are you trying to compile for 32-bit
Cygwin (which is unsupported but should be possible, though I didn't test
multilib sysroots)?  Or are you trying to cross-compile to 32-bit MinGW
(that should absolutely work)?  One of the failed tests that needed
investigation was mingw sysroot trying to use /usr when it shouldn't,
maybe this is what's going on here?
