Pull up revision 1.19 (requested by mhitch in ticket #538):
Add support for aout to ELF conversion to install.md, copied from the sparc
miniroot install.md.  Add usr/bin/file and usr/share/misc/magic to the
miniroot - used by the install.md changes.  Upgrades will now move the
standard a.out shared libraries to /emul/aout.
