I'd suggest you to install to a custom directory, e.g.:

make install INSTALL_PREFIX=c:\lazarus\fpc\2.6.4-debug

and copy over the fpc.cfg from 
c:\lazarus\fpc\2.6.4\bin\i386-win32\fpc.cfg to 
c:\lazarus\fpc\2.6.4-debug\bin\i386-win32 and adjust the paths in there. 
Then you can simply change the compiler executable inside the Lazarus 

- you don't need to specify OS_TARGET and CPU_TARGET if they are the 
same as those of the starting compiler (e.g. you have a i386-win32 
compiler installed and thus OS_TARGET and CPU_TARGET will be "win32" and 
"i386" respectively)
- Lazarus will automatically recompile the LCL and all packages your 
application uses upon the first compilation after you changed the 
compiler; thus the compilation might take longer the first time
