Subject: [PATCH] ref-manual: New BB_GENERATE_MIRROR_TARBALLS variable.

Fixes [YOCTO #5035]

Added a new glossary entry for BB_GENERATE_MIRROR_TARBALLS
and updated the DL_DIR entry to note the ability to get these
tarballs into DL_DIR.  Cross-referenced the new variable
from DL_DIR as well.

(From yocto-docs rev: 361000877f2a13b13154e437a6c28839fa58cd5e)
