Tested crisv32-linux (much as you can do without actually installing a new /lib/ld.so.1 with the changed defaults). Yep, this is actually a change of the default in glibc (port to be submitted), but changing it this way is safe: with old libraries lacking a note, they default to not having an executable stack, as should be. You pragmatically only need an executable stack for the gcc test-suite, AFAIK. :) Committed. Tested cris-elf and crisv32-elf too with some other patches FWIW.
Emit executable-stack note correctly for CRIS targets. * config/cris/cris.c (cris_file_end): New function. (TARGET_ASM_FILE_END): Define.
