Fix a bug in the slave serial programming mode for the Xilinx
Spartan2/3 FPGAs. The old code used "< 0" on a "char" type to test if
the most significant bit was set, which did not work on any
architecture where "char" defaulted to be an unsigned type.
Based on a patch by Angelos Manousaridis <amanous@inaccessnetworks.com>
