busybox build does not reproduce #1636
Description
I compared a CI build of #1630 with my local build, the only remaining reproducibility issue is busybox. All coreboot stages now reproduce, payload differs in the initrd only.
diffoscope identifies busybox. There are a lot of differences in disassembly and relocations but I think they all stem from a difference in string data (which causes more layout differences, etc.):

Some date format string changed slightly, now starts with @@@. NO NAME also moved.
(left is CI, right is my local build, and I did a clean build by deleting build/x86 and install/x86 for this)
