source-built aspnetcore fails during rollup on ppc64le

[tmds]

The build is failing as follows:

    > build:debug
    > rollup -c --environment development --forceExit
    
    /home/tester/dotnet/src/aspnetcore/node_modules/rollup/dist/native.js:38
    	throw new Error(
    	^

@javiercn any recommendation regarding this one? Is this an important step that is required to run as part of the build, or can it be skipped on this particular platform?

@mthalman, @MichaelSimons do you know if this distro is something we MUST support or not?

[javiercn]

@mkArtakMSFT this might require installing "@rollup/wasm-node" and potentially overriding rollup with an npm override.

ppc64le is community supported meaning principally community-driven contributions with best effort support from Microsoft.

Comparing rollup with System.Runtime.InteropServices.Architecture, it looks like rollup doesn't support a number of .NET architectures, including loongarch, ppc64le, s390x and x86.

Looks like there is already some community effort to get a s390x build of rollup going: rollup/rollup#5346 ... I'll see if can help that succeed.

@Swapnali911 @janani66 there's a similar PR for ppc64le: rollup/rollup#5350. You may want to look into that.

this might require installing "@rollup/wasm-node" and potentially overriding rollup with an npm override.

@javiercn @mkArtakMSFT does "@rollup/wasm-node" provide an alternative option that would work on both ppc64le and s390x?

@tmds will check

So any workaround for now?

[uweigand]

As of version 4.13.1, rollup now supports s390x and provides a linux-s390x prebuilt binary:
https://www.npmjs.com/package/@rollup/rollup-linux-s390x-gnu

What about other OS'es? Having rollup used in build process, makes it "hard" to port to other platforms :)
