Modified Files:
	src/usr.bin/make: config.h job.c

Log Message:
Make it easier for the build environment (such as a configure script)
to override the default shell:

* Rename _BASENAME_DEFSHELL to DEFSHELL_CUSTOM, because it's no longer
  always a basename, it might be a full path;
* Rename DEFSHELL to DEFSHELL_INDEX, because it's actually an index into
  an array;
* Provide symbolic names for the possible values if DEFSHELL_INDEX;
* Document how the build environment may set DEFSHELL_INDEX or
  DEFSHELL_CUSTOM to choose the default shell;
* Move the fallback definition of DEFSHELL_INDEX from config.h to job.c,
  because it's used only in job.c.

Discussed with sjg.
