Re: /usr/sbin/etcupdate -D/usr/obj/DESTDIRs/main-CA7-chroot -s /usr/main-src -M TARGET_ARCH=armv7 ends up building dtc !

It does, but teasing apart what's needed for buildworld/buildkernel and
just buildetc is a bunch of work, and better to have something that
works inefficiently than something that doesn't work. Patches more than
welcome to make it more efficient. However, I will note that 99% of the
time -B is what people should be using, so it's not all that important
(it's rare that you want to produce an etcupdate tree from sources that
haven't just been built).

An example was: `-- /bin/sh /usr/sbin/etcupdate -D/usr/obj/DESTDIRs/main-CA7-chroot -s /usr/main-src -M TARGET_ARCH=armv7 `-- make TARGET_ARCH=armv7 -DNO_FILEMON buildetc `-- make -m /usr/main-src/share/mk -f Makefile.inc1 TARGET=arm TARGET_ARCH=armv7 buildetc `-- make -f Makefile.inc1 _bootstrap-tools MK_CROSS_COMPILER=no MK_TOOLCHAIN=no . . . `-- /bin/sh -e -c echo "===> usr.bin/dtc (obj,all,install)"; cd /usr/main-src/usr.bin/dtc;. . . install `-- make DIRPRFX=usr.bin/dtc/ all `-- c++ -O2 -pipe -fno-common -DNDEBUG . . . -c /usr/main-src/usr.bin/dtc/fdt.cc -o fdt.o More may build. This is just what was present when I happened to look. Seems an odd thing to be happening for an etcupdate . I'll note that aarch64 targeting aarch64 (self hosted build) also spends notable time and is likely doing similarly. === Mark Millard marklmi at yahoo.com
