Subject: package/zstd: build multithreaded host-zstd
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=e3110b3c635264f5f3a97100c837e7881c5898ec;p=buildroot.git

package/zstd: build multithreaded host-zstd

Under the assumption that all Buildroot build hosts nowadays are
multithreaded, we can boost performance of host-zstd by enabling
multithreaded operation.
