I set the following /"/QMAKE_LFLAGS_SONAME     = -Wl,-soname=" i am 
unsure if this is functionally equivalent to my change, hopefully i will 
get a chance to try it later today.

This provides a improvement for me but it is not a complete solution, on 
android we load libQt5xxx.so my solution as it was still tried to load 
libQt5xxx.so.5 which doesn't exist as libraries are not symlinked on 
android like they are on Linux and only libQt5xxx.so is present.
If there is a way to tell cmake to specify NEEDED as libQt5xxx.so 
instead of libQt5xxx.so.5 in a CMakeLists.txt or in the toolchain files 
then a solution that achieves the same result as mine is correct. I 
didn't spend a great deal of time working on a solution for this second 
part, the one or two things i tried, mainly removing version numbers in 
the cmake toolchain files didn't help so i went back and wrote a script 
that modified the make files to have -soname=libQt5xxx.so instead of 
-soname=libQt5xxx.so.5 which does work without changes to cmake, i just 
couldn't figure out how to make the Qt configure scripts generate this.

I will test your change in the next day or two but i suspect it won't be 
a complete fix.
