Support Ash

[carolynvs]

I use Ash, it seems here -f is an illegal option: -sh: export: line 51: illegal option -f Can we introduce a check to support Ash? via @zs-zs

Testing under Ash reported this error.

Although I'm not familiar with Ash, I think if has several differences from bash/zsh.

Hi, I saw that you created an issue based on my comment, thanks for that!
@ibigbug Yes, this happens when you run the script as it is. I think I already reported this issue both here and on the Carina forums. As a workaround I found it out if I run this preprocessing statement before I execute the script, it works:

sed -i -e 's/\${BASH_SOURCE\[0\]}/\$0/g' /home/docker/.dvm/dvm.sh

But now I have to introduce another replacement which is a bit silly, that's why I made the comment. :)

PS.: I'm also not very familiar with Ash, but this is what I have currently. Maybe there is a smarter solution I just don't know about.
