Same problem occurs with make -j1 and with -platform linux-clang provided as an option to ./configure.
Similar problem occured with 5.8.0, iirc. I can re-verify on request. Compilation of Qt 5.7.1 works fine.

Note: After finishing ./configure I get a warning: "WARNING: Cross compiling without sysroot. Disabling pkg-config"

Going to make a guess here since you are using Gentoo..

Do you have the proper cryptographic stuff enabled in your kernel? I don't know if QCryptographicHash relies on anything from there, but that's what makes it a guess. ;)

I say this because I have definitely built Qt for andriod on gentoo before without seeing this issue. Only thing that pops into my header when I looked at the problem.

Edit: Just reread your post and saw the cross compiling without sysroot error. This could be cause it as well if it doesn't have the proper (i.e. compiled for ARM) libs that it needs to build the cryptographic stuff. This is more likely than my above suggestion, and something you should look into before messing with the kernel. Especially now that I realize your target kernel won't be the same anyway since it's on an android device.

Yes, I can confirm same error. I usually build Qt from git on Windows (crossplatform build to Android). And yesterday I did 'git pull', configure and make. Then I got that error after some time. So it's a problem.

qqmltypeloader.cpp

I found a workaround. You have to add '#include' line to fix this problem.
