Embedded system on Linux

[Vance Shipley]

Currently embedded systems are only built for Solaris.  This is too 
strict for our liking here.  In fact we have built and used embedded 
Erlang/OTP systems on both Unixware and Linux.

Below is a patch for R7B to get an embedded system built and working
under Linux (at least RedHat 6.2).
