Libraries missing DT_SONAME

[pfn]

Lack of DT_SONAME on native libraries leads to an annoying error popup on Android N-preview,

please add -Wl,-soname,libXXXXX.so to the linker flags for at least the libraries below, thanks!

Sure, but do you know why we need to specify the soname manually?

I don't know why it's being flagged now, but soname is typically used for
library versioning. I don't know why the makefiles for these aren't already
setting them. It should be an automatic part of any library build...

[saudet]

JavaCPP is its own little build system, and there's no versioning for DLLs on Windows, so it just doesn't do any of that for portability reasons.

It's kind of strange that Android now requires something used for versioning, while it doesn't even support versioning itself. Oh well, whatever.

Fix included in version 1.2. Thanks for reporting!
