Subject: [Buildroot] [PATCH 3/4] configs/snps_archs38_hsdk_defconfig: switch to glibc hard-float

Vineet, All,

On 2021-01-15 12:03 -0800, Vineet Gupta spake thusly:
> We are no longer actively working on uClibc and hard-float support is
> pretty stable, so make that default for HSDK boards
> 
> The hard-float setting is a bit convulated since current ARC gcc lacks
> --with-fpu - so this is done with BR2_TARGET_OPTIMIZATION

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.
