Log message:
cross: Replace RMD160 checksums with BLAKE2s checksums

All checksums have been double-checked against existing RMD160 and
SHA512 hashes

The following distfiles could not be fetched (some may be fetched
conditionally):

./cross/avr-gcc/distinfo isl-0.24.tar.bz2

Log message:
cross: Remove SHA1 hashes for distfiles

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:
cross/*: let pkglint autofix indentation and variable alignment

pkglint -Wall -F -r cross

xtensa-esp32-elf-gcc has been manually edited afterwards because when
realigning variable assignments, pkglint only allows one long outlier
line. This package has two long SITES.* lines, therefore pkglint wanted
to indent the variable values much further to the right. This needs to be
fixed in pkglint.

Log message:
objconv: Fix distfile fetching.

The distfile is unversioned and replaced every time a new version is
released, so keep a DIST_SUBDIR'd copy on MASTER_SITE_LOCAL.

Log message:
Mark as broken on big endian systems because they're not supported.
On Darwin/PowerPC, build reports:
"This machine has big-endian memory organization. Objconv program will not \ 
work"

Log message:
Add SHA512 digests for distfiles for cross category

Existing SHA1 digests verified, all found to be the same on the
machine holding the existing distfiles (morden).  Existing SHA1
digests retained for now as an audit trail.
