Previously, MAKESYSPATH as well as '-m' directives in MAKEFLAGS would cause any port rebuilt during the PORTS_MODULES stage to consume system makefiles from $(SRCROOT)/share/mk instead of those installed under /usr/share/mk. For kernel modules that need to build against an updated src tree this makes sense; less so for <bsd.port.mk> or any userspace library or utility the port may also happen to install. Before 11.0, this probably didn't matter much in practice. But the addition of src.libnames.mk under $(SRCROOT)/share/mk in 11.0 breaks any consumer of bsd.prog.mk and DPADD/LDADD during PORTS_MODULES. Address the build breakage by removing MAKESYSPATH and any occurrence of '-m' from MAKEFLAGS in the environment created for the port build. Instead set SYSDIR so that any kmod built by the port will still consume conf/kmod.mk from the updated src tree, assuming it uses <bsd.kmod.mk> Reviewed by: bdrewery MFC after: 2 weeks Differential Revision: https://reviews.freebsd.org/D13053

For copyright information, please see the file COPYRIGHT in this directory (additional copyright information also exists for some sources in this tree - please see the specific source directories for more information).
The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree. See build(7) and https://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html for more information, including setting make(1) variables.
The buildkernel and installkernel targets build and install
the kernel and the modules (see below). Please see the top of
the Makefile in this directory for more information on the
standard build targets and compile-time flags.
Building a kernel is a somewhat more involved process. See build(7), config(8), and https://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html for more information.
Note: If you want to build and install the kernel with the
buildkernel and installkernel targets, you might need to build
world before. More information is available in the handbook.
The kernel configuration files reside in the sys/<arch>/conf
sub-directory. GENERIC is the default configuration used in release builds.
