Hi, here're 2 patches that remove libdelayimp.a and liblargeint.a, which are not
only empty, but also nearly never used. It's worth noting that libdelayimp.a is
actually irrelevant to the "delay loading" feature, instead, this is provided by
delayimp.c, which is linked into libmingwex.a.

Subject: [PATCH 1/2] crt: Remove empty library libdelayimp.a
This library has no source, and searching GitHub show no real users.
