build: hppa is weird

hppa (yes, HP PA-RISC) apparently creates relocations that refer to
".init+0x12345" for everything, referencing way past the end of the
.init section.  While this is only fallback code hit when XREF_SETUP()
is missing (i.e. the FRRouting.XREF ELF note is absent), try to make it
work anyway.
