[PATCH] fix build on uClibc

Currently we fail on uclibc like below

GCC detects that we call 'restrict' as param name in function
signatures and complains since both params are called 'restrict'
therefore we use __restrict to denote the C99 keywork

This only happens of uclibc since this code is not excercised with
eglibc otherwise we will have same issue there too
