with openssl from ports.

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.

sysutils/u-boot-tools: fix build on non-arm non-x86

Changing target to tools-only_defconfig will omit the parts that need EFI and
will still build the binaries this port needs.

sysutils/u-boot-tools: Update to 2020.04

u-boot-tools builds fine with default python

With hat:	portmgr

Mark as BROKEN on powerpc64:

  include/config_distro_bootcmd.h:279:3: sandbox EFI support is only supported
on ARM and x86

This is even after adding the fix for 12-STABLE of compiler:c11 to USES,
which at least allows the build to get that far.

I took a look at this one time, thinking it would be easy, but I was not
able to come up with a quick answer.

CLeanup u-boot-tools
- Do not overwrite do-build, it is not necessary
- Ensure the env variables are respected during configure phase
- Now that we use the regular do-build kernel we can pass gmake variables via
  arguments which allows to overwrites predefine ones without custom patches
- Force verbose mode when building to see what command line is invoke, in in
  particular which compiler is called
- Overwrite NOSTDINC_FLAGS because on freebsd we do actually want to use our
  regular standard include files
- Register the dependency on libssl/libcrypto

Add new port sysutils/u-boot-tools

U-Boot tools for creating and analyzing u-boot images.
U-Boot images are used to embed kernels into a know format for u-boot.
It can also be FIT (Flattened Image Tree) images when the source describing
the image is written like a DTS (Device Tree Source).
