I am attempting to build Rust through the Spack package manager using the Intel Classic compiler suite. On a couple of different machines, when I export CC=icc and Spack runs the following command:
'./configure' '--set' 'install.prefix=/opt/spack_nov23/var/spack/environments/intel/install/linux-centos8-zen3/intel-2021.10.0/rust-1.73.0-loiur4ftbc2h7ssh6c4iakogxt662geh' '--s
et' 'install.sysconfdir=etc' '--set' 'build.extended=true' '--set' 'build.docs=false' '--set' 'build.cargo=/opt/spack_nov23/var/spack/environments/intel/install/linux-centos8-zen3/intel-2021.10.0/rust-bootstrap
-1.73.0-wwn45x3ghjbu4ambymj2d6tpz2duvgb3/bin/cargo' '--set' 'build.rustc=/opt/spack_nov23/var/spack/environments/intel/install/linux-centos8-zen3/intel-2021.10.0/rust-bootstrap-1.73.0-wwn45x3ghjbu4ambymj2d6tpz2
duvgb3/bin/rustc' '--set' 'llvm.download-ci-llvm=false' '--tools=cargo,rustdoc,clippy,src,rustfmt'
it fails on the "Compiling build_helper v0.1.0" step trying to generate "build/bootstrap/debug/deps/bootstrap-8d477eb8daba6006" with the following error:

Building bootstrap
Is it possible to compile Rust with CC=icc, or does it need gcc/clang?
