PS1, Line 7: Remove 'm4'
maybe: remove explicit install of 'm4'

https://review.coreboot.org/c/coreboot/+/82512/comment/e774e1f7_3098ce4a?usp... :
PS1, Line 9: Remove m4 as it depends on flex and bison.
Maybe:
`Remove m4 as an explicity installed package as it will be
installed automatically by flex and bison.`
