Patch from Emmanuel Raguet <raguet@crf.canon.fr> and Eric Valette

<valette@crf.canon.fr> to add a port of the GoAhead web server
(httpd) to the RTEMS build tree.  They have successfully used
this BSP on i386/pc386 and PowerPC/mcp750.

Mark and Joel spoke with Nick Berliner <nickb@goahead.com> on
26 Oct 1999 about this port and got verbal approval to include
it in RTEMS distributions.
