[PATCH] crosssdk/nativesdk: Ensure EXTRA_OECONF_FPU is unset

[Richard Purdie <richard.purdie@linuxfoundation.org>]

If EXTRA_OECONF_FPU is left set, certain ARM variables related to hard-float
can get pulled in and trigger rebuilds of the crosssdk code. The best solution
is to simply force the variable to a known correct value for the SDK targets
currently supported in the same way as TARGET_FPU.

There is some slight rearrangement of the gcc code to ensure the variable is
always used to call the fpu function.
