Created attachment 367812 [details, diff] autogen-cross-compile.patch It has never been possible to cross-compile autogen because it builds its own documentation. The HDEPEND variable allows us to rely on the host autogen for this. The ebuild changes required are fairly minimal. I noticed that, even without this fix, autogen seems to build a second time during "make install". I don't know why and unfortunately I don't have time to find out.
please don't post patches that rely on unofficial EAPIs as there's no chance of them getting committed to the tree
Sorry, I saw "experimental" but did not take that to mean "unofficial". I now see it is still under debate. I'll add bug #317337 as a dependency in case the situation improves. This bug also serves as an interesting use-case.
