>Description:

I am probably missing something, but if you grep for "-mfloat-abi=soft"
or "-msoft-float" in the build log of an eabi arm build for hard float,
there are lots of hits. One arbitrary example:

State-Changed-From-To: open->closed
State-Changed-By: martin@NetBSD.org
State-Changed-When: Tue, 10 Jul 2018 13:55:23 +0000
State-Changed-Why:
Joerg pointed out that this is building parts of commpat libs, so -msoft-float
is fine.
Actually the only compiler invocations with -msoft-float but no -mabi= are
in the sanitizer lib builds, so everything is fine.
