0) rename UNPRIVILEGED UNPRIVED. It was too long. We'll argue about if
we should replace it with yet something else later. It currently
logs metadata by default. We'll argue more about that later too.
1) create a _SRC_TOP_OBJ_ variable pointing at the /usr/src objdir so
we know where to dump metadata.
2) Add a METALOG variable pointing at the default location for the
metadata log. (This may be moved or renamed -- the location is just
for testing.)
3) Add a HOST_INSTALL_FILE used in host tools Makefiles instead of
INSTALL_FILE, which doesn't include ${INSTPRIV} (i.e -U -M ${METALOG})
4) Add INSTALL_LINK, INSTALL_SYMLINK for use in other .mk files so we
can get rid of explicit uses of ln. Slightly clean up INSTALL_FILE.
It is infeasible for some ARM ports to use anything but ELF/new-toolchain,
and this allows for the ARM ports that aren't ready for ELF to stay at
MACHINE_ARCH == arm32 until they're ready. The rest of the ARM ports
have a userbase such that if a flag day happens with the compiler (there
are a couple of ABI issues still being discussed), that it won't matter
so much.
Discussed with Ben Harris, Matt Thomas, and Chris Gilbert.
* Rewrite src/tools Make logic to work like the rest of the tree wrt
"dependall" and "install". The old "make build" hack is gone.
* Remove the MKTOOLS logic. This was linked to the "make build" hack,
and was only needed because TOOLDIR originally had no writable default.
* Redo the GNU configure/make logic to make it fit reasonably in a
BSD make wrapper. Use new ${.ALLTARGETS} variable to scan for
targets in $(srcdir), and mark them with .MADE: to prevent rebuilding.
* Only build cross tools in src/tools; remove some messy logic in
src/usr.* and src/gnu/usr.* that would do target filename rewriting
(improves consistency and readability).
* Add the ability to build cross gdb at tool build time by setting
MKCROSSGDB (default no) to "yes" in mk.conf.
* Add src/tools/groff and set up paths to work with this cross groff.
