    nvramtool: Allow build under Cygwin
    
    To build under Cygwin, nvramtool depends upon the package ioperm:
    http://openwince.sourceforge.net/ioperm/
    
    for sys/io.h and sys/perm.h.  This change causes the nvramtool make to correctly include and link against these headers and libraries.
