Can not build with out support for hard or symbolic links.

[John E. Malmberg]

The file RSYNC.H always defines the macros SUPPORT_LINKS and 
SUPPORT_HARD_LINKS.

#define SUPPORT_LINKS HAVE_READLINK
#define SUPPORT_HARD_LINKS HAVE_LINK

Everywhere that RSYNC uses SUPPORT_LINKS and SUPPORT_HARD_LINKS it is 
testing if the macros are defined, not what their values are.

This results that the code will always be built with support for hard 
and symbolic links.
