Cygport-0.37.0-1 appends "noarch" to all mingw64 release packages

[Carlo B.]

Hello,
after upgrading to Cygport-0.37.0-1, I discovered that all binary
packages created with MinGW-w64 have a "-noarch" suffix appended to
their name.
Binary and debuginfo packages are affected, source packages are not.
This is an example output when I tried to refresh one of my packages:

mingw64-x86_64-bzip2-1.0.8-1-noarch.hint
mingw64-x86_64-bzip2-1.0.8-1-noarch.tar.xz
mingw64-x86_64-bzip2-1.0.8-1-src.hint
mingw64-x86_64-bzip2-1.0.8-1-src.tar.xz

Is it normal or it is a bug?

Sincerely,

Carlo Bramini.
