Docker compatibility: makefile and headers (#17)

* Docker compatibility: makefile and headers
- _GNU_SOURCE required for F_SETSIG
* Remove duplicate makeright.sh script
* Update some includes that don't exist on modern Linux (termio.h); Clang in Docker
  has trouble resolving them automatically

-# Feb. 6 1990 osamu: Add display option
-#		     release option does not support yet.

-# Jul 18 1990 JDS:  Add 'init' option for making init-loading emulators
-#
-# Mar 7 1991 JDS:  Add '3' option for making 3-byte emulators.
-#
-# usage:  makeright [display-option] [other-option]
-# 
-# example: makeright single	;  make lde for mmaped displayFB
-#	   makeright multi	;  make lde for cg3,cg6
-#	   makeright x		;  make lde for X-windows
-#	   makeright color	;  make lde with color support in it.
-#	   makeright multi release ; make release version of lde for cg3,cg6
-#	   makeright init	;  make lde for loading INIT.DLINIT b/w only
-#	   makeright x 3	;  make lde for X-windows, 3-byte-atom version.
-#
-# makeright multi requires directory "maiko/${osversion}.${architecture}-multi"
-# (ex. maiko/sunos4.sparc-multi)
-# object files are stored there.
-#
-# makeright init  requires directory "maiko/init.${architecture}
-#
-# Note: X11R4 environment link shared libraries. 
-#	lde need X library. If lde links shared libraries, 
-#	X shared libraries are needed at run time.
