Steps to reproduce

The cxxflags variant doesn't seem to accept certain types of flags:

> spack spec cmake cxxflags="-stdlib=libc++"
==> Error: {'-stdlib=libc++'} does not equal set()

Curiously, e.g.

> spack spec cmake cxxflags="-stdlib=libc+"

or

> spack spec cmake cxxflags="-stdlib=libc+++"

or

> spack spec cmake cxxflags="-O3"

do concretize (is -stdlib=libc++ being filtered out at some point?).

Error message

> spack -d spec -lI cmake cxxflags="-stdlib=libc++"

Information on your system

The assertion points to

spack/lib/spack/spack/solver/asp.py

Line 2304 in 194f9a9

assert set(compiler_flags) == set(ordered_compiler_flags), msg
which was introduced in #34218. Concretization works before that was merged.
