Ilya Leoshkevich c10e0627c7 s390/module: fix loading modules with a lot of relocations ...

commit f3b7e73b2c upstream.

If the size of the PLT entries generated by apply_rela() exceeds
64KiB, the first ones can no longer reach __jump_r1 with brc. Fix by
using brcl. An alternative solution is to add a __jump_r1 copy after
every 64KiB, however, the space savings are quite small and do not
justify the additional complexity.
