You're welcome. I also just noticed that the test program fails when
compiling with --enable-small. The attached patch fixes the problem.

Lastly, a minor thing: with --enable-small I get the following warnings:
CC	libavutil/xtea.o
libavutil/xtea.c: In function ‘xtea_crypt_ecb’:
libavutil/xtea.c:45: warning: unused variable ‘k3’
libavutil/xtea.c:44: warning: unused variable ‘k2’
libavutil/xtea.c:43: warning: unused variable ‘k1’
libavutil/xtea.c:42: warning: unused variable ‘k0’
