[Buildroot] build failure mbstate_t not declared

[Joseph G. Boike]

Hi,
I checked out the latest buildroot and tried to build it but keep 
getting errors regarding mbstate_t not being declared.
Here's a section of the output (there are many more lines with the same 
error, but I wanted to keep the post short.)
Any suggestions?
Regards,
Joe
