[OE-core] [PATCH][RFC] cortexa8: use hard floating point

[Darren Hart]

>From what I could gather, it makes sense to address using mfloat-abi=hard
for the beagleboard in the cortexa8 tune file. Before I submit this as a pull
request, I'd appreciate a sanity check from the Beagleboard experts.

Is there any reason the cortexa8 tune file should not be using "hf" by default?

Thanks,

Darren

--------
Fixes [YOCTO #1203]

mfloat-abi is currently set to soft for beagleboard (cortexa8) and needs to be
set to hard to take advantage of the floating point hardware.

Append "hf" to each of the cortexa8 TUNE_FEATURES and PACKAGE_EXTRA_ARCHS
variables. This enables "callconvention-hard" from the included
arch-armv7a.inc.

Add a missing closing quote to the VFP AVAILTUNES append operation.
