Author: bdrewery Date: Mon Apr 18 18:14:02 2016 New Revision: 298219 URL: https://svnweb.freebsd.org/changeset/base/298219 Log: Cause an error during 'make install' if trying to compile with CC. This is limited to src-tree builds, meaning not extended to ports or other out-of-tree builds. This will help ensure that read-only OBJDIRS will be respected at install-time by causing a more consistent failure for those who don't use a read-only OBJDIR. It also will cause Jenkins to yell. This is a better solution than trying to see CC=false as has been attempted and discussed before. Of course this is only relevant for files generated by CC. Disable this for META_MODE since it will detect the CFLAGS/command change and force a rebuild.
