So this is because jabberd2/util/crypt_blowfish.c has:

#ifdef __i386__
#define BF_ASM                          1
...

but then doesn't include the actual assembly implementation of x86.S [1] 
Since this file has the comments:

 * This version of the assembly code is optimized primarily for the original
 * Intel Pentium but is also careful to avoid partial register stalls on the
 * Pentium Pro family of processors (tested up to Pentium III Coppermine).
 *
 * It is possible to do 15% faster on the Pentium Pro family and probably on
 * many non-Intel x86 processors, but, unfortunately, that would make things
 * twice slower for the original Pentium.

I've just changed that #define BF_ASM to 0, rebuilt the package and 
[BOB]'s your mother's brother.
