It is slightly more complicated - the fdt_check_full function exists
in all the distros we target AFAICT, but libfdt's ELF symbols file
never recorded its existance. So if you static link to libfdt you
get fdt_check_full but if you dynamic link it is inaccessible :-(
I see, that's where the 1.5.1 version comes from then.
