This failed for me with an i386/host and both ia64/amd64 targets.  The error 
   /home/scole/nbsd/cvs/src/crypto/external/bsd/openssl/dist/crypto/bn/bn_asm.c(28): syntax error 'ret' [249]
 is caused by int128 & uint128 not being available on 32 bit hosts.

Mainly for my own future recollections, here is some info from web searching, not sure if it is completely accurate:

 - GCC supports built-in __int128 and __uint128 types on 64-bit platforms
 - Before version 4.6.0 they were named __int128_t and __uint128_t
 - can view #defines in gcc with "gcc -dM -E -x c /dev/null"
 - __SIZEOF_INT128__ would be defined if int128 is supported, so 
   #if defined(__SIZEOF_INT128__)
   ...
   #endif

I included a patch below which allows the build to complete, but it is not correct.  It looks like someone was already aware of the issue, but I didn't see an existing PR so I submitted this one.

Also, might want to revisit the xlint build workaround in http://gnats.netbsd.org/53710 if a real solution can be implemented.

>How-To-Repeat:
run build.sh with MKLINT=yes in mk.conf on 32 bit host cross-compiling 64 bit target

i386-host> env MAKECONF=mk.conf ./build.sh -j 6 -U -u -m amd64 -x -X ../xsrc release

>Fix:
This patch allows to the build to complete, but is not a real fix.
