Build failure on Fedora 28

[Yasumasa Suenaga]

Hi all,

I tried to build OpenJDK (jdk/jdk) on Fedora 28 x64, but it failed as following:

```
[ysuenaga at fc28 jdk]$ make images
Building target 'images' in configuration 'linux-x86_64-normal-server-fastdebug'
gmake[3]: *** [GenerateLinkOptData.gmk:64: /home/ysuenaga/OpenJDK/jdk/build/linux-x86_64-normal-server-fastdebug/support/link_opt/classlist] Error 1
gmake[2]: *** [make/Main.gmk:448: generate-link-opt-data] Error 2

ERROR: Build failed for target 'images' in configuration 'linux-x86_64-normal-server-fastdebug' (exit code 2)

No indication of failed target found.
Hint: Try searching the build log for '] Error'.
Hint: See doc/building.html#troubleshooting for assistance.

make[1]: *** [/home/ysuenaga/OpenJDK/jdk/make/Init.gmk:305: main] Error 2
make: *** [/home/ysuenaga/OpenJDK/jdk/make/Init.gmk:186: images] Error 2
```

It seems "interim-image" is not valid:

```
[ysuenaga at fc28 jdk]$ ./build/linux-x86_64-normal-server-fastdebug/support/interim-image/bin/java --version
Error occurred during initialization of VM
java/lang/NoClassDefFoundError: java/lang/Object
```

It can succeed on Fedora 27. So I think it causes by OS.
I've disabled SELinux, and warnings / errors are nothing in `journalctl -a`.

Do you have any idea to resolve this issue?


Thanks,
