With your patch it gets past that point of build failure.

But my devel/amd64-gcc predates the removal of float.h from
the installed devel/amd64-gcc so the following may not be as
it would be in such a context:

--- lib/msun__L ---
/usr/src/lib/msun/src/catrigl.c:90:2: error: #error "Unsupported long double format"
 #error "Unsupported long double format"
  ^~~~~
. . .

I can remove float.h and see what happens.
