[Rust] Rust library hashes

[Sandro Mani]

Hi

I'm packaging mingw-rust, and while everything compiled, the RPM build 
fails with

BuildError: The following noarch package built differently on different 
architectures: mingw32-rust-debuginfo-1.38.0-1.fc32.noarch.rpm
rpmdiff output was:
removed 
/usr/i686-w64-mingw32/lib/rustlib/i686-pc-windows-gnu/lib/std-667f9119009aea97.dll.debug
added 
/usr/i686-w64-mingw32/lib/rustlib/i686-pc-windows-gnu/lib/std-adb8e1a97c54d6f2.dll.debug
[etc]

So indeed I suppose the hashes used in the libraries vary depending on 
various factors, possibly the architecture of the host system. Anyone 
has an idea how to deal with this, or make the hashes stable between 
host arches?

Thanks
Sandro
