Hi 叶雨飞,
only the maintainer can release it.

However to see how to build and test it, the easy way
is to download the cygwin source package
    mingw64-x86_64-binutils-2.28.1.12c1f20d-1-src.tar.xz
using setup or directly from a mirror.

The file contains the upstream source used for the build,
a patch and the cygport file.

$ tar -tf mingw64-x86_64-binutils-2.28.1.12c1f20d-1-src.tar.xz
mingw64-x86_64-binutils-2.28.1.12c1f20d-1.src/
mingw64-x86_64-binutils-2.28.1.12c1f20d-1.src/binutils-gdb-2.28.1.12c1f20d.tar.bz2
mingw64-x86_64-binutils-2.28.1.12c1f20d-1.src/config-rpath.patch
mingw64-x86_64-binutils-2.28.1.12c1f20d-1.src/mingw64-x86_64-binutils.cygport


cygport is the standard method for building and maintaining packages for
the Cygwin distribution.
https://sourceware.org/ml/cygwin-announce/2017-05/msg00042.html

Attached for your convenience the same patch and the modified
mingw64-x86_64-binutils.cygport for 2.19.1.

Assuming you have cygport and all the needed tools and libraries,
these commands will download the upstream source file and
build the full cygwin package

$ cygport mingw64-x86_64-binutils.cygport download
$ cygport mingw64-x86_64-binutils.cygport almostall

The build took ~ 1 hour on my PC.
I have not yet tested it.

Regards
Marco
