* Fix tecmake to set a soname for the libraries
This currenly fails strict-policy checks because the package doesn't
depend on libstdc++.so, but this should be in haiku$secondaryArchSuffix.
I also had to explicitly depend on the proper version of as, otherwise
the one for gcc2 would be picked up. I suspect one of the dependencies
is wrong, but attempts to use haikuporter --why have failed.
* Rebase the work I did against latest IUP release
* Currently fails to build because IUP wants to generate both Lua 5.1
and 5.2 bindings. It seems we can't build_require both packages to build
the bindings ? (require should be ok, as the libs for each version will
go in different packages in the end).
* Also, port some of the fixes to tecmake to the two other tecgraf libs
using it.
