But I would consider those very special cases and wouldn't want to pollute
the linker to work around those special cases.

The easiest (to me) solution is to put the routines into the system C
library.  You'd drop the special millcode conventions, but that's a
small price given that the only ones you probably call with any
regularity are div/mod in which case the cost of reloading the pic
registers is dwarfed by cost of the divide.

Then for the kernel you just put the needed routines (probably just
$$div, $$divU, $$rem, $$remU) into arch/parisc/support.S.
