From: Christian Marangi Date: Wed, 17 Apr 2024 09:28:58 +0000 (+0200) Subject: tools: zstd: update patch with upstream version X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=2b6923bc7601c732a62d0e169c69106638af0a84;p=openwrt%2Fopenwrt.git tools: zstd: update patch with upstream version Proposed fixup has been replaced and merged with an advanced version. install-pc-mt has been dropped and replaced for intall-pc MT=1 to generate a .pc file with multithread libs.
