I had exactly the same problem with openssl. I fixed it by simply pulling off several checks (ie the file-exist-checks simply refused to work in crosscompile mode) and recreated configure. The tests I removed were meaningless for my platforms nevertheless. But the problem is another point: autoconf is not really made for crosscompiling. the support for different tool commands and the so called "crosscompile support" (simply disable a bunch of checks or refuse to work when it doesnt know what to do now) is just an ugly hack, neither are sysroot builds supported in any way. To get a really reliable solution for that, we need an new, well designed universal toolchain frontend. this of course could also be shipped with apache for a while (-> "vendor branch" ... grrmpf). > But the Makefiles still won't work since they have no separate of host > and target $CC etc, yet need to build and run executables on the host > system in several places.

We need at least an *clear* distinction between host und and target compilation. These are all questions for the unitool, which I already announced here.
