The referenced change made NO_INSTALLLIB, NO_MAN, and NO_PROFILE into
errors causing these ports that declare them and use the FreeBSD make
infrastructure as part of their build to fail.
When the offending variables occur in a BSD Makefile, NO_MAN becomes
MAN= and NO_INSTALLLIB and NO_PROFILE become MK_INSTALLLIB=no and
MK_PROFILE=no respectively. When declared in the environment they
become WITHOUT_<FOO>.
Also GC NO_MANCOMPRESSED which doesn't do anything.
In the case of devel/libpasori, this change accomplished the same thing
as the change in r518434, but more directly (fix the Makefiles rather
than patching them after they are installed).
