The reason will be displayed to describe this comment to others. Learn more.

The SYSROOT environment variable is being exported but appears to be unused. The wasixcc toolchain (installed via the wasix-org/wasixcc action) manages its own sysroot internally, and the wasix-configure-eh.sh script no longer references this variable. Consider removing this line to avoid confusion.
