Well, with a cache variable, you can either ensure that it is exported
in the environment prior to configure, e.g. for bash:

export lt_cv_add_cstd_crun=no
./configure; make

or you can add it to the configure arguments:

./configure --enable-foo --with-bar lt_cv_add_cstd_crun=no --prefix=/opt/baz

Would that be sufficient? (Note that the name of the variable is subject
to change).
