Andrew Childs 2a9b3b4943 cc-wrapper, bintools-wrapper: support MACOSX_DEPLOYMENT_TARGET with roles ... In a typical build environment the toolchain will use the value of the MACOSX_DEPLOYMENT_TARGET environment variable to determine the version of macOS to support. When cross compiling there are two distinct toolchains, but they will look at this single environment variable. To avoid contamination, we always set the equivalent command line flag which effectively disables the toolchain's internal handling. Prior to this change, the MACOSX_DEPLOYMENT_TARGET variable was ignored, and the toolchains always used the Nix platform definition (`darwinMinVersion`) unless overridden with command line arguments. This change restores support for MACOSX_DEPLOYMENT_TARGET, and adds nix-specific MACOSX_DEPLOYMENT_TARGET_FOR_BUILD and MACOSX_DEPLOYMENT_TARGET_FOR_TARGET for cross compilation.		2021-04-11 09:47:10 +09:00
