Bug#824449: firefox: FTBFS on sparc64 due to wrong platform definitions

Sun Dec 11 23:20:32 UTC 2016

Attaching my latest patch which makes use of the ARM64 memory allocator, both for the
Javascript engine as well as mozjemalloc. It seems to fix the memory corruption and
allocation issues, but Firefox now crashes with SIGBUS in the xulrunner stub (see
below).

If anyone wants to have a go at this, just get the source of the current firefox
package in Debian (version 50) and apply the patch with "patch -p1", then run
"dpkg-source --commit" in the source tree to apply the patch to quilt.

Thanks,
Adrian
