Undefined reference to `le32toh'

when cross-compiling radiotap, there is no `le32toh" definition:
https://github.com/radiotap/r.

take a look, in the header file endian.h defined,
and then can not find out where the header file endian.h,
kernel include does not contain
is defined in the c library?
