Dear Maintainer,

scilab FTBFS on ppc64el with the following error:

| checking if jni.h can be included... yes
| configure: error: Could not detect the location of the Java
|             shared library. You will need to update java.m4
|             to add support for this JVM configuration.

A full build log is available here:
https://buildd.debian.org/status/fetch.php?pkg=scilab&arch=ppc64el&ver=5.5.0-3&stamp=1410496986

As suggested by the error message, here is an update of m4/java.m4 to
support ppc64el. I have also changed the machine for ppc64 big endian,
which use the same directory as the little endian version. I guess it
was wrongly set as a 32-bit powerpc machine can run a 64-bit kernel.
Packages should be built using the linux32 wrapper on such machines.

Would it be possible to apply this patch in the next upload? Thanks in advance.
