Cross-Compiling SSH Server

[Rick Woodring]

Clearing the CPP environment variable got configure to go until it
reached an error about zlib not being found.   I addedd --disable-zlib
to the configure command line and that appears to have made configure
work normally.  I was able to compile with "make dropbearmulti" but I
have not tested it yet on my target machine.

Thanks
