<p dir="auto" style="color: #3a383f; margin: 0 0 1rem;" align="initial">This change instead addresses the "custom make" build interface, where the Makefile would look something like this:</p>

<p dir="auto" style="color: #3a383f; margin: 0 0 1rem;" align="initial">And currently this will not include ABI_FLAGS when linking.</p>
<p dir="auto" style="color: #3a383f; margin: 0 0 1rem;" align="initial">It might be that using the "custom make" build interface like this without using the dedicated $(make-exe) macro (which does pull in ABI_FLAGS) is an unsupported use-case. But given that it is available with no clear warning signs, it might be worth fixing?</p>
<p dir="auto" style="color: #3a383f; margin: 0;" align="initial">(We use this "custom make" interface at $(dayjob), and I have previously spent some time trying to figure out why I was getting hard-float newlib at link-time when I was otherwise building the application and BSP with soft-float.)</p>
