Comment (by barracuda156):

 Okay, that is genuinely opportunistic linking, code is correct:
 {{{
 /opt/local/bin/g++-mp-12 -std=gnu++17 -dynamiclib
 -Wl,-headerpad_max_install_names -undefined dynamic_lookup -single_module
 -multiply_defined suppress

 }}}

 At the same time, after current update of oneTBB this should not occur,
 since libexec will not be in default search path. I assume.
