[oe] [PATCH][meta-oe 2/3] nodejs: force use of -mfpu-abi=soft for ARMv5

[Otavio Salvador]

The build system defaults to 'softfp' but this use hardware
instructions that are not available making node to fail to run on
ARMv5 based CPUs. Now we check if TARGET_FPU is 'soft' and change the
default of the build system so it works.

Tested on i.MX233 (ARM926EJ-S)
