  1. Enable zstd for debug compression. 

    Set LLVM_ENABLE_ZSTD alongside LLVM_ENABLE_ZLIB so that --compress-debug-sections=zstd is an option.
Use static linking to avoid a new runtime dependency. Add an llvm.libzstd bootstrap option for LLVM
with zstd. Set it off by default except for the dist builder. Handle llvm-config --system-libs output
that contains static libraries.

  4. Install zstd in dist builder image. 

    Build libzstd from source because the EPEL package is built without fPIC.
