It seems that a BOM marker sneaked in:

$ od -c 3rdparty/nod/Makefile.am
0000000 357 273 277   i   n   c   l   u   d   e       $   (   t   o   p
0000020   _   s   r   c   d   i   r   )   /   c   o   n   f   i   g   /
0000040   c   o   m   m   o   n   .   a   m  \n  \n   E   X   T   R   A
0000060   _   D   I   S   T       =       n   o   d       \  \n  \t   R
0000100   E   A   D   M   E   .   m   d  \n

I'm going to remove it.
