svn commit: r307967 - head/usr.sbin/config

[Marcel Moolenaar]

Author: marcel

New Revision: 307967
URL: https://svnweb.freebsd.org/changeset/base/307967

Log:
  Allow config to be compiled from another source directory, such as one
  for building tools. This boils down to replacing ${.CURDIR} with
  ${SRCDIR}, where the latter is the directory in which this makefile
  lives.
  
  Also allow overriding where file2c comes from using ${FILE2C}.
