Log message:
*: remove pkg-config from tools where no buildlink3.mk file is included

Bulk build on NetBSD of these packages had the same result as before
(build succeeds, no PLIST change).

SHA512 hashes.

Log message:
all: migrate some SourceForge homepage URLs back from https to http

https://mail-index.netbsd.org/pkgsrc-changes/2020/01/18/msg205146.html

In the above commit, the homepage URLs were migrated from http to https,
assuming that SourceForge would use the same host names for both http and
https connections. This assumption was wrong. Their documentation at
https://sourceforge.net/p/forge/documentation/Custom%20VHOSTs/ states
that the https URLs use the domain sourceforge.io instead.

To make the homepages from the above commit reachable again, pkglint has
been extended to check for reachable homepages. This check is only
enabled when the --network command line option is given.

Each of the homepages that referred to https://$project.sourceforge.net
before was migrated to https://$project.sourceforge.io (27), and if that
was not reachable, to the fallback URL http://$project.sourceforge.net
(163).

Log message:
all: migrate several HOMEPAGEs to https

pkglint --only "https instead of http" -r -F

With manual adjustments afterwards since pkglint 19.4.4 fixed a few
indentations in unrelated lines.

This mainly affects projects hosted at SourceForce, as well as
freedesktop.org, CTAN and GNU.

Log message:
enable for all platforms, and pass --disable-sse on non x86 platforms.

with this, audacity runs fine on arm64.

Log message:
audio/libsbsms: fix typo in BROKEN_EXCEPT_ON_PLATFORM

Log message:
Fix indentation in buildlink3.mk files.

The actual fix as been done by "pkglint -F */*/buildlink3.mk", and was
reviewed manually.

There are some .include lines that still are indented with zero spaces
although the surrounding .if is indented. This is existing practice.
