[tex-live] Erors rebuilding format after updating TexLive 2016 with tlmgr

[David Carlisle]

> Could this missing * cause the compilation failure ?

probably yes, prefixing a format name with * was the old way of
selecting etex extensions, before the -etex option was added. Your
error message that \numexpr is not defined shows that is the
underlying problem, that you are building a classic tex format, not
one with etex extensions.
