Consistent checks for asm .symver and version-script
Use the same checks for asm .symver and -Wl,--version-script
support for both libgphoto2.la and libgphoto2_port.la.
This also reorganizes the Makefile.am files for libgphoto2.la
and libgphoto2_port.la so that things belonging together are
actually grouped together, so that inconsistencies can become
more visible.
This does not change what actually happens with when linking
the libraries:
* libgphoto2.la is still linked with just a
--export-symbols libgphoto2.sym
list of exported symbols.
* libgphoto2_port.la is still linked with a
-Wl,--version-script=libgphoto2_port.ver
version script.
However, the two library Makefile.am are now organized
in such a way that you can actually see that.
We should examine what those two symbol export methods actually
do on Linux/ELF (complete support for version script semantics),
and on non-ELF systems such as MacOSX dylib or Windows DLL.
