patch 9.1.1307: make syntax does not reliably detect different flavors

Browse Source 
Problem:  GNU extensions, such as `ifeq` and `wildcard` function, are
          highlighted in BSDmakefile
Solution: detect BSD, GNU, or Microsoft implementation according to
	  filename, user-defined global variables, or file contents

closes: #17089
