Depends, the duplication is small anyways as linux.h is only 129 lines
(including copyright and comments).
In fact it is way wrong now anyways as there is no uclibc for hurd.
So the duplication factor should not matter as there is hardly any
duplication.
Only the following code will be duplicated which is hardly any after
all:
