🚀 go-pugleaf

I compiled gs for my AT&T 3b1.  I doesn't have X, so I deleted the
references to the X device from the Makefile.  I picked pbm, pbmraw
dfaxhigh and dfaxlow as the devices compiled in.

I found a couple of problems.  The 3b1 has no gettimeofday.  Thus I
modified the routine that returns the time to simple use time() and
ignore the milliseconds (the 3b1 isn't fast enough for this to be a
problem!).  The stat structure does not have a blocksize, so I made
a change for that.  Diffs for these are enclosed.  The only other
thing is there is no rename() function.  I have a library with a few
miscellaneous routines in it one of which is rename, so I didn't
modify gs itself for this one.  A simple link/unlink would probably
suffice.
