Me neither - last I tried on sparc64 it was only usefull for a very
limited set of binaries and far from trivial to fix.

There were bugs in the mmap emulation and newer Solaris needed
additional syscalls for ld.elf_so. I put fixing it somewhere on my todo
list (and even have some diagnostic kernel modificiations to make it
print out more stuff before binaries fail), but the fixing part had no
chance to bubble up into visibility of the front page there for a year
or so and unlikely is going to happen anytime soon. Better fish to fry
elsewhere...

So I won't object removal from the sparc64 PoV.
