Problem building installable toolchain

[Stephen Street <stephen@streetfiresound.com>]

Hello,

I'm new to the openembedded project and I'm having problems building an
installable toolchain (i.e. bitbake meta-toolchain).  I have
successfully integrated a new machine and distro configuration (see
below).  I can build this configuration using bitbake task-base and
everything appear to works.  When I try to build a toolchain using
"bitbake meta-toolchain" or "bitbake meta-sdk" the "gcc-cross-sdk-4.1.1"
package fails to build.  These following snippet show the error:

This appears to be a problem with the header configuration but I'm a not
a toolchain expert.  Has anyone encountered this problem before?  How
should I approach resolving this problem?

Following are my configuration files and attached is the full log
