Here we are placing constant values that have relocations into mergeable
sections,
many linkers don't support handling of that merging that section so they ignore
the
mergeability bit at that point. So instead just place them into the normal
readonly section.
Note categorize_decl_for_section will do this already for generic decls,
this just fixes the rtx constant pool selection.
Bootstrapped and tested on x86_64-linux-gnu.

gcc/ChangeLog:
* varasm.cc (default_elf_select_rtx_section): If there are relocs,
select readonly data section instead of mergeable sections.
