It seems you are missing the libfdt headers, so indeed you found bug.

Replacing CONFIG_FITLOADER by CONFIG_FDT in hw/core/Makefile.objs and 
default-configs/mips64el-softmmu.mak should fix it, can you try?

It'd be useful if next time you also tell which compiler/version are you 
using.

And also the ./configure output, I'm interested by:

"fdt support       no"
