Log message:
bootstrap-mk-files: Update to 20240422.

Remove OS variable from remaining sys.mk files.  This was never defined on a
few operating systems (including NetBSD), is not used by pkgsrc, and wasted a
fork of a shell and uname(1) in every bmake call on many systems.

Log message:
bootstrap-mk-files: Remove Bitrig support

Log message:
Update to 20230509. Changes:

- OpenBSD: don't install catpages by default.

While here, fix pkglint warnings.

Log message:
bootstrap-mk-files: Do not overwrite OBJECT_FMT.

Fixes builds on macOS.  Bump version to 20230225.

Log message:
bootstrap-mk-files: Set OBJECT_FMT=ELF in bsd.own.mk.

mips64eb is not on a.out, but the outdated bsd.own.mk conditionals
selected that for it.  This now matches modern NetBSD, as of 2008 --
everything's on ELF, nothing on a.out or COFF any more.

Log message:
bootstrap-mk: Remove GCC/Clang-specific warning flags

These are leftover from the NetBSD base system where having lots
of specific warning flags makes sense because the system is compiled
with -Werror, but here they just cause portability problems.

Reported as breaking the bootstrap on HP-UX by Lehel Bernadt on
pkgsrc-users@.

Log message:
Fix bootstrap on QNX

Tested with QNX 6.5.0SP1.

Two things were needed:

 * bootstrap needs to export ACCEPT_INFERIOR_RM_PROGRAM=yes on QNX,
   because libarchive checks for "rm -f" (with no arguments) working in
   configure. It doesn't seem to actually use it during the build, so
   this works.
 * QNX.sys.mk sets LORDER to echo, but sets TSORT to tsort -q. This
   results in tsort complaining about having an uneven number of inputs,
   since of course there are no dependency pairs.
   Hence, if LORDER is overridden to echo, TSORT also needs to be
   overridden to cat. Interestingly, Linux.sys.mk also sets LORDER=echo
   and TSORT=tsort -q, so it's surprising this isn't broken as well?

Log message:
all: migrate homepages from http to https

pkglint -r --network --only "migrate"

As a side-effect of migrating the homepages, pkglint also fixed a few
indentations in unrelated lines. These and the new homepages have been
checked manually.

Log message:
All Minix supported platforms are ELF.
Confirmed with bsd.own.mk in Minix 3.4RC6 base.

Log message:
Minix does support shared libraries (tested on 3.4RC6).
