Author: imp
Date: Sat Dec 5 00:15:04 2015
New Revision: 291828
URL: https://svnweb.freebsd.org/changeset/base/291828
Log:
Minor cleanup in how we run make:
o Move SRCCONF and __MAKE_CONF into the environment to cope with
file paths with spaces in them better.
o Move the rest of the variable setting command line args into
__MAKE_CONF files.
o Trace the commands that we're using to build so they appear at the
top of the log.
o Be more consistent about quoting paths for cd and similar commands
to better cope with paths with spaces in them, though some more
work is likely needed.
o Add some comments about all this.
o Minor formatting tweaks in a couple places
