[meta-freescale] Yocto dizzy version 1.7.1 cross compiling meta-toolchain BROKEN for weeks now!

[ad me]

All,

We have been observing this bug for many weeks now, hoping the dizzy build
will be updated to fix this. It looks like it is not getting any attention.
Please help!
Any quick solution while waiting for a git repository fix?

There is a problem with this “dizzy” toolchain. though the environment
above shows this board used hard-float VFP, it looks like soft float is
used somewhere and __ARM_PCS_VFP is not defined.

Here is the version of gcc set up by the environment above:

If you go to , you will notice that it is checking for “#if !defined
__ARM_PCS_VFP”.

This somehow is not defined.

Even when I try to hack it by putting “#define  __ARM_PCS_VFP 1” at the top
of my , I get the linker error below, which implies intermediate files were
built with __ARM_PCS_VFP not defined.
