added libraries: opus flac libsndfile updated: libvorbis libogg openal - Everything works as expected for now. Bare in mind libsndfile needed the check for whether or not it could find the xiph libraries removed in order for this to work.

dnl We want to know if GCC stack protector works, for the C and for the C++
|
|
dnl compiler.
|
|
dnl
|
|
dnl Just checking if the compiler accepts the required CFLAGSs is not enough
|
|
dnl because we have seen at least one instance where this check was
|
|
dnl in-sufficient.
|
|
dnl
|
|
dnl Instead, try to compile and link a test program with the stack protector
|
|
dnl flags. If that works, we use it.
