.NET SDK for Android + `$(EnableLLVM)`=True + `$(AotAssemblies)`=True + Windows: bad path quoting?

[jonpryor]

Description

AOT + LLVM doesn't work with .NET SDK for Android apps.

Reproduction Steps

1. dotnet new android -n android

2. Edit android\android.csproj, and add:

      <PropertyGroup Condition=" '$(TargetFramework)' == 'net6.0-android' And '$(Configuration)' == 'Release' ">
        <EnableLLVM>True</EnableLLVM>
        <AotAssemblies>True</AotAssemblies>
      </PropertyGroup>

3. Build! dotnet build -c Release -v:diag > b.txt

Expected behavior

Success!

Actual behavior

ºFails to build:
