[Jiří Vaněk]

> Unluckily, ShenandoahGC in jdk11 i still disabled by default. In addition, its output is broken:
> 
> 
> checking for dlopen in -ldl... yes
> checking if shenandoah can be built... checking if zgc can be built... no, platform not supported
> checking if jvmci module jdk.internal.vm.ci should be built... yes
> 
> 
> In all other JDKs it is enabled by default, and prints correctly yes/no:
> 
> checking for dlopen in -ldl... yes
> checking if shenandoah can be built... yes
> checking if zgc can be built... yes
> checking if jvmci module jdk.internal.vm.ci should be built... yes

> This PR is fixing this. In jdk17 and up , when manually disabled, the "no" is printed.
