Hi rustaceans.
I am trying to compile my project using the toolchain nightly-x86_64-pc-windows-gnu but I am hitting some GNU assembler errors: 'File too big' and too many sections (42346).
I am trying to compile in Windows 10 64bit, using version gcc.exe (x86_64-posix-seh-rev0, Built by MinGW-W64 project) 8.1.0.
Here's the relevant compilation error. Interesting part is around cargo:warning= lines.
Error
The following warnings were emitted during compilation:

Seems there's a solution available:
https://stackoverflow.com/questions/16596876/object-file-has-too-many-sections
But no idea how to enable that option when targeting nightly-x86_64-pc-windows-gnu
How can I overcome this issue?
