> {{{-a}}} is **intentional** : either Makevar file could be a symlink to
a machine- or project-specific Makevar file, and Sage should respect this
if it has been so positioned by the user.
If you think that `-f` will not work with symlinks, you are mistaken.
Being a file and being a symlink are independent. In particular, a symlink
to an existing file is considered to be both a file and a symlink.
You really want to use `-f` here, since `-a` will match directories (and
other weird things like devices,...) and you don't want that. Moreover,
`-f` is more portable than `-a`.
