u64rol should be declared 'inline' when compiling sha512.c, and 'extern 
inline' when compiling u64.c.

My guess is that a 'make bootstrap' will fix the problem.

If not, what is the output of 'nm -o u64.o sha512.o | grep u64rol'? It 
should be something like this (with more 0s on a 64-bit build):

   u64.o:00000000 T u64rol
   sha512.o:         U u64rol

and the definition in u64.o should satisfy the use in sha512.o. If not, 
please look at the preprocessed output when compiling u64.c. That output 
should contain something like this:

   # 200 "u64.h"
   extern inline u64
   u64rol (u64 x, int n)
   {
     return ((((x) << (n))) | (((x) >> (64 - n))));
   }

and if it doesn't, that's the problem.
