The symbol is present in the 5.8.0 version in the build tree, but not in the
installed version.

How do I check that?
NB: it's only lrelease that fails, all other build steps complete just fine. I
presume other executables must be called that also require new ABIs/symbols
from
QtCore . Setting LD_LIBRARY_PATH and QT_PLUGIN_PATH by hand I can also run just
about any existing binary against Qt 5.8 .

That's the installed library, not the one it should be using as long as 5.8.0
has not been installed.
Something is different between lrelease and other executables: ldd's output
doesn't change for it when I set LD_LIBRARY_PATH as it does for qtdiag, for
instance. Both result from the same build:
%> env LD_LIBRARY_PATH=/path/to/destroot/opt/local/libexec/qt5angel/lib
QT_PLUGIN_PATH=/path/to/destroot/opt/local/share/qt5angel/plugins:/opt/local/share/qt5/plugins
ldd /path/to/build/qttools/bin/qtdiag
linux-vdso.so.1 => (0x00007ffef63ed000)
