Committed, libgloss: hook up cris-elf to the initfini-array support.
After a binutils change "a while ago" (2015-12) to default to
--enable-initfini-array, i.e. to merge .ctors and .dtors into
.init_array and .fini_array, this is needed for cdtors to run at all.
Based on what goes on in arm/ and aarch64/. Tested for cris-elf by
running the gcc testsuite.
By the way, the configure test doesn't detect this change, so the
HAVE_INITFINI_ARRAY ifdeffery is somewhat redundant. Still, the
change is tested to be safe with older binutils too.
libgloss/
* cris/crt0.S, cris/lcrt0.c: Include newlib.h.
[HAVE_INITFINI_ARRAY] (_init): Define to __libc_init_array.
[HAVE_INITFINI_ARRAY] (_fini): Ditto __libc_fini_array.
