[tex-live] luaotfload tries to recompile an existing .luc file

Dear Christophe,

The current value of TEXMFCACHE in
/usr/local/texlive/2016/texmf-dist/web2c/texmf.cnf
and
/usr/local/texlive/2016/texmf-dist/web2c/texmfcnf.lua
is
TEXMFCACHE = $TEXMFSYSVAR;$TEXMFVAR

What happens if you set
TEXMFCACHE = $TEXMFVAR
in your own texmf.cnf and texmfcnf.lua
in, for example, /usr/local/texlive/texmf-local/web2c/ ?

Best,
Akira
