Disable jemalloc on aarch64/powerpc

alexcrichton · alexcrichton · commit de80670f7487 · 2016-10-27T08:08:33.000-07:00
Sounds like jemalloc is broken on systems which differ in page size than the host it was compiled on (unless an option was passed). This unfortunately reduces the portability of binaries created and can often make Rust segfault by default. For now let's patch over this by disabling jemalloc until we can figure out a better solution. Closes #36994 Closes #37320 cc jemalloc/jemalloc#467
