Why is this guarded by .MAKE.LEVEL 0?
.MAKE.META.IGNORE_* should be largely irrelevant at level 0
which in the DIRDEPS_BUILD is reserved for orchestration.
Even in the legacy build, level 0 would be just the top-level makefiles
and anything dealing with meta files would be expected to be level 1 or
greater. =

Depending on value of MAKEOBJDIR the above may not work at all.
The default is
share/mk/src.sys.obj.mk:_default_makeobjdir=3D $${.CURDIR:S,^$${SRCTOP},$$=
{OBJTOP},}
In which case the above would not be correct.
