- Subject: [Xtensa] update linker scripts for exception tables
I've committed this patch to treat the exception tables for Tensilica's XCC
compiler in the same way as GCC's exception table sections: if they're
read-only, they go in the read-only text segment; otherwise, they go with the
"RELRO" sections.

* emulparams/elf32xtensa.sh (OTHER_READONLY_SECTIONS): Add ONLY_IF_RO
for .xt_except_table.
(OTHER_RELRO_SECTIONS): New.
