Does not run shell properly on MacOS

[sealad886]

Trying to run the build.sh and tarb.sh shell scripts fails due to how MacOS interprets sed command; requires backup file extension as first command.

% bash -x ./build.sh arm64

• echo

• set -eu

• sh -n tarb.sh

• TMPDIR=build
  ++ awk '/^#binaries.tgz.base64/ { print NR + 1; exit 0; }' tarb.sh

• BIN_LINE=1142

• offline=false

• '[' .arm64 '!=' .o ']'
  ++ head -n1 CHANGELOG

• ver='v2023.10.22 202310220'

• echo 'v2023.10.22 202310220'

• cut -d ' ' -f 2

• sed -i '/^VERSION=/s/=.*/="v2023.10.22 202310220"/' tarb.sh
  sed: 1: "tarb.sh": undefined label 'arb.sh'

To fix this, simply find-and-replace in both build.sh and tarb.sh files:
sed -i
-->. sed -i ""
such that the first arg is "" after -i. If you don't have a trailing space after either in your find-and-replace, then your arguments line up perfectly for how MacOS expects this to work and the shell scripts will run correctly.
