From b346fa58b15b9880b714c6f0cc4dddaf84d3da6f Mon Sep 17 00:00:00 2001 From: Chris Packham Date: Sun, 29 Aug 2021 21:27:29 +1200 Subject: cc/gcc: Add options for zstd usage GCC can support using zstd compression for LTO object files. By default GCC's configure will enable this if libzstd is installed on the machine building the toolchain. This may be undesirable if the toolchain is to be used on a different machine. Add an option to control zstd usage and set the default to the same as the current behaviour (i.e. auto).
