Forced to install an optional package.

[Nick-Miras]

I am running PlatformIO on Gentoo. When I tried to initialize a new project for an a9g board, it gave me an UnknownPackageError regarding waybyte/toolchain-gccmipselfrda8955. After reading the package description of gccmipselfrda8955, it should only work on Windows operating systems; however, after reading the platform.json file of this repository, the package should be optional. What could be the issue here?

Result of uname -r:

6.6.13-gentoo

Complete error message:

Tool Manager: Installing waybyte/toolchain-gccmipselfrda8955 @ =4.4.2
UnknownPackageError: Could not find the package with 'waybyte/toolchain-gccmipselfrda8955 @ =4.4.2' requirements for your system 'linux_x86_64'

Edit:
I've read the platform.py file and discovered that it is indeed required if the chipset is rda8955. However, it stumps me that the toolchain is only available for Windows. Are there any alternative packages in Linux?
