odroid-mali: mark package as BROKEN

The version of the khrplatform.h header bundled with odroid-mali has a
definition of the khronos_intptr_t and khronos_ssize_t that doesn't
match the official Khronos registry headers or the Mesa3D headers. Due
to this, it causes conflicts with some packages that redefines those
types (with the correct definitions), such as libepoxy.

Issue reported upstream at: https://github.com/mdrjr/c2_mali/issues/1

Since nobody bothered fixing the issue even though it has been happening
since July 2016 (first build failure at
http://autobuild.buildroot.net/results/ed8d562ae5fdb472a83f9a07b2f755c80c972c34/),
let's mark this package as BROKEN.

Fixes:
