Well this is interesting and I'll have to dig around some more but
here's what I've found after doing a build.  It looks like I have
SPARC ELF ABI compatibility on my x86_64 Ubuntu 14.04.1 machine.  I
can execute the test app since it's statically linked.

# ./tryancilautoclose
Unsupported ancillary data: 65535/1
# echo $?
111
# file tryancilautoclose
tryancilautoclose: ELF 32-bit MSB  executable, SPARC version 1 (SYSV),
statically linked, with unknown capability 0x41000000 = 0xf676e75,
with unknown capability 0x10000 = 0x70403, not stripped
