Yes. Patch attached (build-tested only). I was able to reproduce the
reported FTBFS in my sid sbuild chroot, and the same chroot can build
my patched version successfully.

It looks like you uploaded libvorbis 1.3.4 the same day, and that new
upstream version correctly moves -lm from Libs to Libs.private in
vorbis.pc:

https://anonscm.debian.org/cgit/pkg-xiph/libvorbis.git/tree/vorbis.pc.in?h=upstream&id=37c68547f31da4590a31baa0e17c00f20523a9b9

libtheora was built against the older libvorbis, so it had the
implicit -lm borrowed from libvorbis. A rebuild no longer gets that.
