Hi Ali,
Sorry for the delay.
Cross-build failed - missing the stdio.h same as yours on Fedora 30 and 35.
checking gcc-powerpc64-linux-gnu.x86_64 and 
gcc-powerpc64le-linux-gnu.x86_64 packages, both do not ship stdio.h and 
other header files: pthread.h, inttypes.h, etc...

We are investing this issue.
