Hi,

In Android NDK r11 and up there is a bug in GCC which causes this to 
happen, so in order to compile Qt, you have to use Android NDK r10e. 
Since Google has deprecated GCC now, they do not intend to fix this 
problem, but their replacement, clang, currently creates too large 
binaries to be usable for us. They are looking into this problem, 
though. You can follow and join the discussion here:
