You might try the symbol __arm__ for this.  If you need more detailed
version (arm sub-architecture) then have a look at the cpp_cpu_arch 
definitions in gcc spec file (gcc -dumpspecs will show this).

Note that this sort of coding makes it hard to cross-compile your 
package.  A more traditional way to achieve the same goal is to use
either autoconf or just to call "uname -a" from the makefile to determine
the system type.
