Linux AArch64 build fails with missing include <features.h>

[dprogm]

What is the issue?

When compiling a simple program that includes the <algorithm> header the compiler is raising the following error:

external/toolchains_llvm~override~llvm~llvm_toolchain_llvm/bin/../include/c++/v1/__config:261:14: fatal error: 'features.h' file not found
#    include <features.h>

How did you compile?

Used this .bazelrc

build --cxxopt=-std=c++17 --enable_bzlmod --incompatible_enable_cc_toolchain_resolution

On which platform did you compile?

AArch64 Linux, Ubuntu 22.04

What version did you use?

Version 0.10.3 with LLVM 17.04

This looks like a sysroot issue?

features.h is a libc header. Short of a resolution on #155, you need to install glibc in your OS.

On Ubuntu 22.04, unless you are cross-compiling, the apt package libc6-dev is what you need (although it almost always comes preinstalled).

sudo apt-get install libc6-dev && (dpkg -L libc6-dev | grep features.h)

If this is not enough, please reopen the issue.
