[Buildroot] Float error on SAMA5D3 Xplained using nodejs

["Cédric HEYMAN" <c.heyman@til-technologies.fr>]

Hello,

Trying to use nodejs's npm (built with buildroot 2014.11) on SAMA5D3 
Xplained returns following error : 'ERROR: Binary compiled with 
-mfloat-abi=hard but without -DUSE_EABI_HARDFLOAT'

Looking in nodejs.mk shows that : 
'....
NODEJS_CPU = arm
# V8 needs to know what floating point ABI the target is using.  There's 
also
# a 'hard' option which we're not exposing here at the moment, because
# buildroot itself doesn't really support it at present.
ifeq ($(BR2_SOFT_FLOAT),y)
NODEJS_ARM_FP = soft
else
NODEJS_ARM_FP = softfp
endif
....'

It seems there is no support for 'hard' floating point for now.

To solve that, I intend to force '-DUSE_EABI_HARDFLOAT' in nodejs 
compilation package, but I don't know the way to do that; any advice ?

Another way to solve the problem could be to use 'soft' or 'softfp' floating 
point strategy but menuconfig does not propose this tuning, maybe...

Regards,
