[libcxx-dev] Problem installing libcxx and libcxxabi using Bootstrapping on Amazon Linux 2

[Hasan Marzooq via libcxx-dev]

# ls /usr/local/lib/x86_64-unknown-linux | grep -i libc++.so.1.0
libc++.so.1.0

# ldd -v /usr/local/lib/x86_64-unknown-linux/libc++.so.1.0 | grep -i
libc++.so.1.0
        /usr/local/lib/x86_64-unknown-linux/libc++.so.1.0:

I can try with opt. Can you provide some reference on building opt on Linux?

To override LLVM_BINPATH, do I need to install llvm-config and then
override something like  "LLVM_BINPATH=$LLVM_CONFIG --bindir" ?

Thanks!
