Use the historical object directory format for .Xr build 7 targets. For native-builds and builds done directly in sub-directories the format of

a ${MAKEOBJDIRPREFIX}/${.CURDIR} is used, while for cross-builds

a ${MAKEOBJDIRPREFIX}/${TARGET}.${TARGET_ARCH}/${.CURDIR} is used.

p This option is transitional and will be removed in a future version of .Fx , at which time .Va WITH_UNIFIED_OBJDIR will be enabled permanently.
