The attached patch alows the build to proceed past this obstacle,
although I don't know how patches to this files are supposed to be
handled, or if the build will eventually succeed.
Or why we need to cross-build boehm-gc for the target of a C / C++ /
objc cross compiler in the first place. We didn't one or two weeks ago.
