[Buildroot] [PATCH] package/jemalloc: filter on suported architectures

[Yann E. MORIN]

jemalloc has a hard-coded list of supported architectures, which it uses
to define the minimum alignment for allocations. It whines at build time
(not at configure time) when it does not know that alignment.

Fix that by making jemalloc depend on the known-supported architectures.
