Compiler constraints not respected for external packages #8082
Description
External packages are always concretized using the latest compiler available, regardless of the initial request.
Expected Result
$ spack compiler list
==> Available compilers
-- gcc ubuntu18.04-x86_64 ---------------------------------------
gcc@8 [email protected]
$ spack spec -Il openssl %[email protected]
Input spec
--------------------------------
openssl%[email protected]
Concretized

$ spack spec -Il openssl %[email protected]

Steps to reproduce the issue
Configure Spack with the following packages.yaml:
packages:
openssl:
buildable: False
paths:
[email protected]: /usrand the following compilers.yaml:
