[committed] Fix ICE in pa_elf_select_rtx_section

[John David Anglin]

An ICE was noticed in pa_elf_select_rtx_section building googletest on 
hppa-unknown-linux-gnu.
This change fixes the problem.  It puts function pointer rtx's without a DECL 
in .data.rel.ro.local.

Tested on hppa-unknown-linux-gnu.  Committed to trunk and gcc-9 branch.
