Revert "openjdk-8: fix build for gcc8.x"

This reverts commit 52fb41cec7d5125bb11c718705158696ffef11f8.

The change being reverted has two problems:
- it still doesn't produce working binaries
- compilation on pre-gcc v7 compilers fails (which is
  relevant for compiling openjdk-8-native, as that
  uses the build machine's gcc, not yocto's gcc):
  | At global scope:
  | cc1plus: error: unrecognized command line option ‘-Wno-stringop-overflow’ [-Werror]
  | cc1plus: all warnings being treated as errors

We now use a different approach to address the issues
than that patch, and it is thusly not needed anymore.

We fully support gcc < 7 again.

-Subject: [PATCH] openjdk-8: hotspot: fix gcc8 compilation
-
-As oe-core/yocto-project master migrated to gcc8.x we need to support this.
-Therefore disable following gcc warnings/errors which caused the build to fail:
-  + stringop-overflow
-  + return-type
