Added Files:
src/usr.bin/make/unit-tests: meta-ignore.inc
Log Message:
Add unit-tests for .MAKE.META.IGNORE_*
These unit-tests should only be run if TEST_MAKE
has a valid .MAKE.PATH_FILEMON to indicate that filemon is
supported.
All three tests use the same meta-ignore.inc
which runs three sub-makes
one to initialize the target .meta file
two to ignore a file using .MAKE.META.IGNORE_{PATHS,PATTERNS,FILTER}
three to verify that without .MAKE.META.IGNORE_* the target is out of date.
Fix the order of _SED_CMDS to avoid errors when ${MAKE:T} appears in
.OBJDIR
