net-print/starcupsdrv/files/starcupsdrv-3.6.0a-build-fix.patch

Fix ebuild file and src code for cross compilation.

1. Fix dependency check (use compiler preprocessor instead of checking path existence).
2. Use flags like $(CC), etc. for cross compilation.
3. Remove inline for clang linker to find definition (compiler unfolds leaf function as optimizations).
4. Allow parallel compilation.
