Log:
  Remove system makefile path directives from env passed to PORTS_MODULES step
  
  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>
