So either sort out your libgdb, which is not part of FPC and needs to be 
copied into the build directory, or build with

make distclean
make NOGDB=1 all

I think that NOGDB is right, but I'm working from memory here. In 
general I build without libgdb at any sign of problems since it's only 
used in the fp (text) IDE, however I've successfully built it on all 
platforms here except ARM (not tested on x64 since I don't have one).
