ASDF:OUTPUT-FILES is allowed to return a second value which, if true,
indicates that the output files should NOT be relocated.

>From the ASDF manual:

@item @code{output-files}
The @code{output-files} method determines where the method will put its
files.
It returns two values, a list of pathnames, and a boolean.
If the boolean is @code{T} then the pathnames are marked
not be translated by enclosing @code{:around} methods.
If the boolean is @code{NIL} then enclosing @code{:around} methods
may translate these pathnames, e.g. to ensure object files
are somehow stored in some implementation-dependent cache.
