That's what pkg-config is for, and libosmocore already installs a .pc file.

Set PKG_CONFIG_LIBDIR in order to pick up the correct libosmocore.
A sane default could maybe be set by the Makefile, meaning that no
special consideration is needed when following the default
recommended build approach as we document on the wiki.

I don't think it makes sense to install libosmocore into the
toolchain's own lib directory.

I don't think it would be additional user-visible steps, and
internally the steps are still the same.

Because building both for host and target would use the same pattern,
and in particular a pattern (pkg-config) which is sadly not well
understood but very handy.
