Create new LuaJIT release

[Douglas R. Reno]

Before we do a new release of BLFS, we should create a new version of LuaJIT.

Follow this procedure:

cd /tmp
git clone https://luajit.org/git/luajit.git
rm -rf luajit/.git
luajit_version=luajit-$(date +%Y%m%d)
mv -v luajit $luajit_version
tar -cJvf $luajit_version-.tar.xz $luajit_version
Upload to anduin

Make a little more script-like.

[Xi Ruoyao]

To be simpler and to avoid a full clone for each update:

First time:

git clone https://luajit.org/git/luagit.git /path/to/luagit

and keep the local copy /path/to/luagit

For each update:

cd /path/to/luagit
git pull
pkg=luajit-$(date +%Y%m%d)
git archive --format=tar --prefix=${pkg}/ | xz -9 > /tmp/${pkg}.tar.xz
scp /tmp/${pkg}.tar.xz anduin.linuxfromscratch.org:<CLASSIFIED>
