Vineet, All,

On 2021-01-15 12:03 -0800, Vineet Gupta spake thusly:

I split that patch in two:
- one commit to switch to glibc,
- one commit to enable hard-float

Since the hard-float, as you noticed, is using a non-conventional way to
passit, so if it truns out to be causing issues, it is easier to revert
if it is in a commit of its own.

Regards,
Yann E. MORIN.
