Andreas Krebbel e6213e09ed S/390: Prevent GOT access rewrite for certain symbols
When dereferencing a GOT slot with lgrl or lg we rewrite this using
larl to get rid of the extra memory access.  However, we cannot do
this for:

- symbols marked for absolute addressing
- symbols at odd addresses (larl can handle only even addresses)

Fixed with the attached patch.

bfd/ChangeLog:

2018-09-17  Andreas Krebbel  <krebbel@linux.ibm.com>

	* elf64-s390.c (elf_s390_relocate_section): Prevent rewriting of
	GOT accesses with larl for ABS or misaligned symbols.
