problem with debug_loc patch

[Richard Henderson]

At least some of the declarations are outside the DWARF2_DEBUGGING_INFO
ifdefs.  You can see this as

../../../src/gcc/dwarf2out.c:2234: warning: `output_loc_list' declared `static' but never defined
../../../src/gcc/dwarf2out.c:2235: warning: `gen_internal_sym' declared `static' but never defined

when cross-compiling to alpha-dec-osf5.1 or powerpc-ibm-aix4.3.3.

When building with the native compilers this is a hard error and
breaks the build.  Would you please fix this?
