commit f5c1a6374aae8be471b895a43359dcff355577f5 Author: Anthony PERARD <anthony.perard@xxxxxxxxxx> AuthorDate: Thu Feb 16 14:10:07 2023 +0000 Commit: Andrew Cooper <andrew.cooper3@xxxxxxxxxx> CommitDate: Thu Feb 16 22:45:20 2023 +0000 libs: Fix unstable libs build with LLVM, auto-generate version-script Unfortunatly, --default-symver doesn't work with LLVM's LD, LLD. Instead, we will generate a temporary version-script. In order to allow regenerating the script, we'll have a different filename. In order to check if the content is up-to-date, we'll always generated it and compare.
