devel/freebsd-gcc*: Update kernel printf format checking for %b
- Permit the l and ll size modifiers to be used with '%b' for GCC 12/13
(GCC 14/15 already permitted these).
- Permit the '#' modifier to be used with %b. This isn't documented but
the RISC-V kernel uses this.

devel/freebsd-gcc*: Fix error in printf0 format checker patch
Fix a mismerge of the printf0 format checking patch from GCC 9 to GCC
12/13. GCC 11 and later don't warn for NULL format strings (instead a
separate nonnull attribute is used). The printf0 format specifier is
left for now to support builds of existing FreeBSD releases but will
be removed in the future.

devel/freebsd-gcc12: fix build with libc++ 17
When building relatively recent gcc ports (with C++ in them) against
libc++ 17, you get errors similar to:

This is because gcc/system.h includes safe-ctype.h which redefines ctype
macros such as toupper, tolower, etc to "poison" them.
However, it should only include the safe-ctype.h header *after* any C++
headers, such as <list>, <map>, <string>, etc, otherwise these might
transitively include internal ctype headers (such as with libc++ 17),
causing the above conflicts.
This commit moves the safe-ctype.h inclusion to later in gcc/system.h,
which solves this issue, and makes it possible to build against libc++
17.

devel/freebsd-gcc12: Use -stdlib=libc++ to use libc++.
Instead of overriding the path and library name of libstdc++, set the
path for libc++ and change the default of -stdlib= from libstdc++ to
libc++.
devel/freebsd-gcc*: Drop stale workaround for arm targets.
This workaround to force -fbracket-depth=512 was removed from lang/gcc
during the upgrade from gcc 4.8 to gcc 5.
devel/freebsd-gcc12: Fix support for FreeBSD kernel printf.
Remove -fformat-extensions and instead follow clang and add a new
format type: __freebsd_kprintf__. This permits removing unsupported
width specifies such as 'D' which conflict with the local %D specifier
used in the kernel which the old -fformat-extensions did not handle.
devel/freebsd-gcc12: Ignore on FreeBSD 12.
The powerpc flavor fails to build on FreeBSD 12.x as GCC does not
install the secureplt.h header for that version (GCC assumes secureplt
is only used on 13.0 and later). In addition, the fixes needed to
build FreeBSD with GCC 12.x are not going to be backported to
stable/12, so just skip this port on FreeBSD 12.
Remove WWW entries moved into port Makefiles
Commit b7f05445c00f has added WWW entries to port Makefiles based on
WWW: lines in pkg-descr files.
This commit removes the WWW: lines of moved-over URLs from these
pkg-descr files.
Approved by: portmgr (tcberner)
Add WWW entries to port Makefiles
It has been common practice to have one or more URLs at the end of the
ports' pkg-descr files, one per line and prefixed with "WWW:". These
URLs should point at a project website or other relevant resources.
Access to these URLs required processing of the pkg-descr files, and
they have often become stale over time. If more than one such URL was
present in a pkg-descr file, only the first one was tarnsfered into
the port INDEX, but for many ports only the last line did contain the
port specific URL to further information.
There have been several proposals to make a project URL available as
a macro in the ports' Makefiles, over time.
This commit implements such a proposal and moves one of the WWW: entries
of each pkg-descr file into the respective port's Makefile. A heuristic
attempts to identify the most relevant URL in case there is more than
one WWW: entry in some pkg-descr file. URLs that are not moved into the
Makefile are prefixed with "See also:" instead of "WWW:" in the pkg-descr
files in order to preserve them.
There are 1256 ports that had no WWW: entries in pkg-descr files. These
ports will not be touched in this commit.
The portlint port has been adjusted to expect a WWW entry in each port
Makefile, and to flag any remaining "WWW:" lines in pkg-descr files as
deprecated.
