The CMUCL bytecode file format in endian-dependent, there's .lbytef
for little-endian and .bytef. 

Could be changed, but I think this isn't a good idea anyway. I don't
think moving compiled files from Solaris/Sparc to Linux/x86 i worth
the performance peneality. And you had a CMUCL runtime on each machine
anyway, so why not recompile and that's it?
