And remove it from individual ports. Use WRK_ENV in custom build
commands where necessary.
FreeBSD make(1) includes /usr/share/mk/sys.mk and that includes
/etc/make.conf if it exists. This happens when you run make in a port
directory but it also happens when the upstream build system uses make.
This commit disables make.conf inclusion in the latter case because
users can define variables like CFLAGS in make.conf that override ports
framework variables and this can cause problems that are difficult to
diagnose.
If there are any build customisations made through make.conf that stop
working because of this commit then they should be made available by the
ports tree through some mechanism, e.g. an option in a port.
Some ports were picking up variables from Poudriere make.conf and
required fixes:
- astro/wmspaceweather x11-clocks/wmcalclock: Add OPSYS to MAKE_ENV.
- games/zhlt: Add ARCH to MAKE_ENV.
- graphics/tachyon: Upstream ARCH is not ports tree ARCH.
Set ALL_TARGET=bsd so upstream ARCH is defined correctly.
Enable multi-threading support while here.
