Fixes problems in a build with MKLLVM=yes HAVE_LLVM=no,
where this error interacted with settings in
src/external/gpl3/gcc/lib/libgcc/Makefile.inc to cause
some object files to be omitted from the libgcc_s library.
the moment, this can only load very simple modules due to missing
symbols. It is being add at this time to make pullups to the
netbsd-7 branch easier. It is not enabled by default in any kernels.
so it performs the test at the time the rule is invoked. We can't
use a ".if defined" test because that would be tested at the time the
sys.mk file is parsed, which may be before CTFCONVERT has been set by
bsd.own.mk.
Remove the now-unnecessary assignment "CTFCONVERT ?= : ctfconvert",
and the similar assignment to CTFMERGE. Now the build logs are not
cluttered by many unnecessary invocations of the ": ctfconvert ..."
when generating html groff runs netpbm behind your back. Needless to
say we don't have netpbm in base, so this fails on a clean install; so
for now disable generating html for /usr/share/doc by default.
Workaround for PR 48970.
It seems that all available document preparation toolchains are made
of fail.
Update the <bsd.doc.mk> infrastructure, and update the docs to match
the new infrastructure.
- Build and install text, ps, pdf, and/or html, not roff sources.
- Don't wire the chapter numbers into the build system, or use them in
the installed pathnames. This didn't matter much when the docs were a
museum, but now that we're theoretically going to start maintaining
them again, we're going to add and remove documents periodically and
having the chapter numbers baked in creates a lot of thrashing for no
purpose.
- Specify the document name explicitly, rather than implicitly in a
path. Use this name (instead of other random strings) as the name
of the installed files.
- Specify the document section, which is the subdirectory of
/usr/share/doc to install into.
- Allow multiple subdocuments. (That is, multiple documents in one
output directory.)
- Enumerate the .png files groff emits along with html so they can be
installed.
- Remove assorted hand-rolled rules for running roff and roff widgetry
and add enough variable settings to make these unnecessary. This
includes support for
- explicit use of soelim
- refer
- tbl
- pic
- eqn
- Forcibly apply at least minimal amounts of sanity to certain
autogenerated roff files.
- Don't exclude USD.doc, SMM.doc, and PSD.doc directories from the
build, as they now actually do stuff.
Note: currently we can't generate pdf. This turns out to be a
nontrivial problem with no immediate solution forthcoming. So for now,
as a workaround, install compressed .ps as the printable form.
"-Os" was specfied when gcc 4.5.x was imported and the commit log says
"-O2 produces much bigger code with gcc 4.5 than it did with gcc 4.1"
but "-Os" disables most inline declarations and makes some applications
much slower. "-O2 -fno-reorder-blocks" seems enough to reduce sizes
and disabling -freorder-blocks wouldn't cause particular performance
impact on ancient m68k machines with small cache memories.

No objection in the thread and "seems fine to me" from mrg@.
