Hi Sebastian,

This also fixes libgnutls detection on Debian testing (and futur
Jessie) and derivatives.

What about [[libgnutls\\(-deb[[0-9]]\\)\\{0,1\\}]] or
[[libgnutls\\(-[[0-9A-Za-z]]\+\\)\\{0,1\\}]] instead.
I don't think the debian specific soname will bump too often but it
could avoid the need for another patch.
