You should probably also try a build using HP's make.  Last time I tried 
to build GDB using HP's make it barfed.  Details in gdb/PROBLEMS.

Given GDB asumes a real compiler, it can work around the problem by 
recommending that GNU make be built/installed first.  I don't know that 
binutils has that same luxury (unless of course someone is going to run 
after GNU make and ensure that that can be built with HP's K&R compiler 
:-/).
