I am confusing you, maybe.
stage0 is not pic. stage0 is non-pic. initram is pic. initram, which
is pic, needs to call stage0, which is not pic.
To add to the fun, stage0 does make one call to initram: it calls

this implies to me that the printk itself is pic, which it is not. Another name?

except that file IS stage0.o. It's stage0 with all the symbols

stage0 is not pic. If we make it pic, it ballons. When gcc generates
PIC code, it still generates relative calls. Gcc is not tremendously
good at generating PIC, what it really creates is "PIC assuming you
use the GNU shared library techniques".
