          Issue ID: 22455
           Summary: Remove useless conditional assignment of
                    DISABLED_TESTS in posix.mak
           Product: D
           Version: D2
          Hardware: All
                OS: FreeBSD
            Status: NEW
          Severity: trivial
          Priority: P1
         Component: druntime
          Assignee: nobody@puremagic.com
          Reporter: bcallah@openbsd.org

posix.mak includes this conditional check:

ifeq ($(OS),freebsd)
DISABLED_TESTS =
else
DISABLED_TESTS =
endif

Which can be simplified.
