Did you mean the

it since they build libraries in subdirectories.  From
libstdc++-v3/configure.ac:

# Multilibs need MULTISUBDIR defined correctly in certain makefiles so
# that multilib installs will end up installed in the correct place.
# The testsuite needs it for multilib-aware ABI baseline files.
# To work around this not being passed down from config-ml.in ->
# srcdir/Makefile.am -> srcdir/{src,libsupc++,...}/Makefile.am, manually
# append it here.  Only modify Makefiles that have just been created.
