Bugzilla Bug 200039

When built on amd64 with the theora USE-flag, capseo needs a 32-bit copy of
libtheora.so:

/bin/sh ../libtool --mode=link g++ -ansi -pedantic -Wall -Wno-long-long
-Wno-unknown-pragmas  -DVERSION="\"0.2.0-dev\"" -DTHEORA=1 -march=athlon64
-msse3 -pipe -fomit-frame-pointer -O2 -DNDEBUG=1   -o cpsplay
../src/libcapseo.la  -lGL cpsplay.o

make[2]: *** [cpsrecode] Error 1

However, the library is not needed at runtime: libtheora is only used by the
cpsrecode tool, which is built for both 32-bit and 64-bit, but only the 64-bit
version is installed.  The best solution would be to prevent the tools from
being built for 32-bit in the first place, but that would require messing with
autotools, so it suffices not to build the 32-bit version with theora support.

Better patch - use multilib.eclass functionality, and disable theora explicitly
instead of relying on that being the default.

thank you very much.

i've added your advice to capseo-0.3.0_pre200712251-r2 :)
