I should have been clearer.  There is "does not work" and there is
"unsound".  If a package is DEPENDS but not bl3, then it is, as Roland
says, legit ot inspect data files, and to see if a program exists.  It
is not legit to compile against the libraries (or I'd argue, against the
headers) or to assume that scripts/programs can be run.

Even with bl3, in the brave new world of cross, one cannot run
programs, but one can AC_TRY_COMPILE -- or however you spell that in
cmake.
