Bug#733310: libgluegen2-build-java: missing architectures support in <glibc-compat-symbols.h>

[Aurelien Jarno]

Package: libgluegen2-build-java
Version: 2.1.3-1
Severity: serious
Tags: upstream patch
Justification: makes other packages FTBFS

libgluegen2-build-java provides a mechanism in <glibc-compat-symbols.h>
to lower memcpy symbols version. This doesn't take care of at least
ia64 and s390x among the official Debian architectures, but at least
arm64, ppc64, sh4, sparc64, and x32 are also affected among unofficial
architectures. This causes other packages to FTBFS, see for example:
https://buildd.debian.org/status/fetch.php?pkg=libjogl2-java&arch=ia64&ver=2.1.3-1&stamp=1387422174
https://buildd.debian.org/status/fetch.php?pkg=libjogl2-java&arch=s390x&ver=2.1.3-1&stamp=1388229627

As this mechanism doesn't really make sense in a distribution context
(the dependencies are handled by the package manager), I would suggest
to simply disable it. This is the purpose of the patch below:
