[oe] gcc-crosssdk-initial can not compile. Get message: this target does not support --with-float

[Martin Ertsås]

Hi.

When trying to compile meta-toolchain, it crashes during
gcc-cross-initial with the error:

this target does not support --with-float
Valied --with options are: arch arch_32 arch_64 cpu cpu_32 cpu_64 tune
tune_32 tune_64

The reason for this is a commit that happened 2012-05-01 in openembedded
core, called "gcc: Grok for callconvention-hard to enable hard float".
Reverting this patches makes it compile, and still I get the
--mfloat-abi=hard when compiling with the resulting toolchain.

I'm compiling on a x64 Linux machine, with the target being a cortexa9
processor. I have the DEFAULTTUNE set to cortexa9hf-neon. What should
the patch do, and what will happen if I disable it?

Best regard
Martin
