The llvm_precompile function checks for the CLANG version available on the machine
using bash regex and searches for fuzzer libraries in a path based on the full CLANG
version number. (e.g. /usr/lib64/clang/15.0.3/...)
However, on the newest Fedora distribution, the path has changed and fuzzer libraries
couldn't be found. Currently, CLANG libraries path contains only major version number
(/usr/lib64/clang/16)
To address this issue, the function has been updated to search only for the major
CLANG version number instead of the full version number. Instead of using clang_version,
the function now uses clang_num because in every Fedora distribution there is directory
or symlink that points to the right CLANG version.
e.g. symlinks
/usr/lib64/clang/13 -> /usr/lib64/clang/13.0.1
/usr/lib64/clang/15 -> /usr/lib64/clang/15.0.3
or directory:
/usr/lib64/clang/16
