Comment (by kencu):

 Due to a number of reported assembler errors (& numerous tickets) when
 trying to compiler newer code with gcc (Fortan, mostly, as I recall), the
 assember in the cctools port was tweaked to call clang as the assember if
 it was installed, instead of using the built-in ancient `gas` assembler.

 ports/commit/7aa2ff679e61f923475b6c2a56958da61205430b#diff-
 b4eaceceeee7a044c27192b65d64a2a9>.

 I suppose it was later decided to make sure a version of clang was
 available that gcc9+ could use, but I would think that is a more debatable
 change.
