r312452-r312512: - Use SRCTOP-relative paths to other directories instead of .CURDIR-relative ones This simplifies pathing in make/displayed output - Use .CURDIR:H instead of .CURDIR to simplify pathing in output, etc

misc replacements of comma with semicolon when pertinent. Uses of commas instead of a semicolons can easily go undetected. The comma can serve as a statement separator but this shouldn't be abused when statements are meant to be standalone.

DIRDEPS_BUILD: Regenerate without local dependencies.

2016-02-24T17:20:11Z

These are no longer needed after the recent 'beforebuild: depend' changes and hooking DIRDEPS_BUILD into a subset of FAST_DEPEND which supports skipping 'make depend'. Sponsored by: EMC / Isilon Storage Division

First pass through library packaging.

META MODE: Don't create .meta files when symlinking sources into the obj directory.

2015-11-25T19:44:43Z

Tracking these leads to situations where meta mode will consider the file to be out of date if /bin/sh or /bin/ln are newer than the source file. There's no reason for meta mode to do this as make is already handling the rebuild dependency fine. Sponsored by: EMC / Isilon Storage Division

META MODE: Prefer INSTALL=tools/install.sh to lessen the need for xinstall.host.

2015-11-25T19:10:28Z

This both avoids some dependencies on xinstall.host and allows bootstrapping on older releases to work due to lack of at least 'install -l' support. Sponsored by: EMC / Isilon Storage Division

Enforce overwritting SHLIBDIR

2015-06-15T15:34:20Z

Since METAMODE has been added, sys.mk loads bsd.mkopt.mk which ends load loading bsd.own.mk which then defines SHLIBDIR before all the Makefile.inc everywhere. This makes /lib being populated again. Reported by: many
