devel/llbuild: improve committed config.h

Indicate that we do support mmap and mallctl.  This disables the use of
sbrk.

Differential Revision:	https://reviews.freebsd.org/D42975

*/*: use USES=sbrk

Replace various BROKEN entries for missing sbrk on aarch64 and risc64
with USES=sbrk.

Fix a few missing entries (generally ports blocked by other
dependences).

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.

One more small cleanup, forgotten yesterday.

Remove # $FreeBSD$ from Makefiles.

Mark BROKEN on riscv64 the same as on aarch64.

Approved by:	portmgr (tier-2 blanket)

Limit powerpc64 breakage to elfv1 (e.g. GCC).

Change cmake default behaviour to outsource.

Ports that build out of source now simply can use "USES=cmake"
instead of "USES=cmake:outsource". Ports that fail to build
out of source now need to specify "USES=cmake:insource".

I tried to only set insource where explictely needed.

Mark as broken on aarch64, and, where appropriate, armvX.

While here, pet portlint.

Mark ports broken on powerpc64, categories d-f.

While here, pet portlint and do some other cleanup.

Update devel/llbuild to SNAPSHOT-2017-12-10.

This update simplifies the build, as upstream has incorporated many of the
patches that used to be in the files directory of this port.  It also
updates the distinfo to fix the previous BROKEN line.

New port: devel/llbuild

llbuild is a set of libraries for building build systems. Unlike most
build system projects which focus on the syntax for describing the
build, llbuild is designed around a reusable, flexible, and scalable
general purpose build engine capable of solving many "build system"-like
problems. The project also includes additional libraries on top of that
engine which provide support for constructing bespoke build systems
(like swift build) or for building from Ninja manifests.
