I've now managed to test it on both Solaris 11.3 and 11.4. However, it
didn't work on 11.4 and in hindsight it's clear why not:
_GLIBCXX_HAVE_SYMVER_SYMBOL_RENAMING_RUNTIME_SUPPORT is always 0 on
Solaris, as explained in this snippet from acinclude.m4:
# The Solaris 2 runtime linker doesn't support the GNU extension of
# binding the same symbol to different versions
