# Build electerm for loong64 (LoongArch64) Linux - Legacy (old world)
#
# This workflow:
# 1. Downloads GCC 8 cross-compiler from Loongnix for old-world ABI
# 2. Builds x64 version with legacy deps to get the asar
# 3. Downloads electron loong64 from Loongnix
# 4. Cross-compile native modules for loong64 with legacy deps
# 5. Merges x64 asar with loong64 electron and native modules
# 6. Uploads tar.gz to GitHub release draft
# 7. Builds deb package and uploads to GitHub release draft
# 8. Optionally uploads to R2
