If the .OBJDIR is set by the Makefile fragments, then MAKEOBJDIRPREFIX
doesn't need to exist before Makefiles are read.
The only difference that may come into play here is the disabling of the
"logical path" (using the PWD environment variable) for .CURDIR, which
currently happens only for MAKEOBJDIRPREFIX. However, this part needs to be
revisited. There are reasons that make(1) should use resolved paths,
ignoring PWD, even without MAKEOBJDIRPREFIX; the same problems can afflict
MAKEOBJDIR and BSDSRCDIR/BSDOBJDIR.
