Don't put it in /opt. For something like a binray emulator /opt
is just silly.
Currently mips and sparc use /usr/gnemul/<opsys>, Linux-ABI for ix86
uses /emul/<opsys>. I'd suggest going for one of those, possibly
the latter (:)).

It does. On Linux-ABI I use e.g. /emul/osr5, /emul/uw7 and /emul/svr4.
Id suggest using /emul/<opsys> for emulations of another operating
system for the same architecture, /emul/<arch>-<opsys> for non-native.
Windows should go into /emul/win64 and /emul/ia32-win32.
