New Revision: 322951
URL: https://svnweb.freebsd.org/changeset/base/322951

Log:
  Respect MK_TCSH with build-tools and native-xtools
  
  This helps reduce the WORLDTMP footprint slightly.
  
  Based on a patch I submitted 5 years ago to GNATS.
  
  PR:		174051
  MFC after:	2 weeks
  Relnotes:	yes (anyone who cross-builds with MK_TCSH=yes will run into
  		     build failures if the host doesn't have tcsh(1))
