FYI, this has now been filed at PR target/126518.
So poked at this for a while this morning. Ultimately landing on this
newlib change as the culprit for the cris-elf regression). I don't know
why (and I'll leave it for Hans-Peter to chase down), but it's unrelated
to your work Roger:

H8: Add support for preinit/init/fini array
This patch adds support for .preinit_array, .init_array, and
.fini_array
for the H8 family when binutils and GCC are configured with
"--enable-initfini-array".
The changes to init.c and fini.c ensure that linker-defined symbols
referenced from C code are not affected by target-specific symbol
naming
conventions. For example, GCC for H8 prefixes external symbol names
with
an underscore, whereas GCC for ARM does not. The asm keyword is used to
associate C identifiers with the corresponding linker-defined
symbol names
in a target-independent manner.
The patch has been tested on H8 wher it enables support for the
initialization and finalization arrays and on ARM in order to
verify that
the changes do not introduce any regressions.

While the newlib patch says it's H8, it also touches those two generic
files (fini.c/init.c) and somehow that's the trigger for the cris-elf
failures:
cris-sim: gcc: c-c++-common/initpri1-lto-static.c -Wc++-compat
execution test

cris-sim: gcc: gcc.dg/constructor-1.c execution test

I'm swamped with a personal item to address and won't be able to further
debug.
