In meta-agl commit 3564e1dd729f8044d3d7bbb8f025e893da4d5716 added code
that is supposed to link /usr/local to /var/local.

This code provided incorrect relative path to /var/local with one
redundant '..' leading to invalid link.

Correct code to make /usr/local link should be

ln -fs ../var/local ${D}/usr/local
