Hi,
PFA assorted ARC changes. Main being a hw config for -mcpu=hs4x which
schedules code for HS48x dual issue pipeline.
Thx,

For the HS48 processor, BR currently builds with -mcpu=hs4x_rel31 which
generates suboptimal code as it inhibits delay slot and back-back ST and so on.
Enable a new variant to build with -mcpu=hs4x for normal codegen.

Those started to be rather long lines, so I split them.

In fact, the only variant that does not have 4K pages is 750d, so I
inverted the logic to:
depends on !BR2_arc750d
So the lines are not too long anymore.
If the situation becones more complex than that, then we could introduce
intermediate symbols, like;
config BR2_ARC_HAS_4K_PAGES
bool
which could then be selected by the variants that do have it, e.g.:
config BR2_archs4x
bool "ARC HS48"
select BR2_ARC_HAS_4K_PAGES
and then the 4K choice would depend on it;
config BR2_ARC_PAGE_SIZE_4K
bool "4KB"
depends on BR2_ARC_HAS_4K_PAGES
I was about to do that, but if 750d is definitely the only variant to
not support those 4K or 16K pages, this would be overkill...

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

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.

Of all those, I only kept adding C++.
None of the other defconfigs enable debug, or disable stripping.
Also, we like our defconfigs to truly be minimal. We could however
accept an additional defconfig with more packages, as a "demo" of sorts,
though. But the selection of packages you added is not kind of "demoing"
that specific board...
So, I just kept C++.
Thanks!
