Suppressing all #ifdefs (in particular in cpu-exec.c) will be 
impossible. But I agree that in many cases it is possible. An important 
point I want to solve is how to build for several target CPUs at once 
(it is very important for easier regression testing). My current idea is 
to build qemu several times and to output object files in separate 
directories (for example the target specifics ones you mention). Then 
you will have several executables: qemu-i386, qemu-arm, qemu-ppc in the 
main directory.
