Fix compile time warning building aout targeted architectures.
Occasionally I build an out-of-tree a.out target (m68k-amigaos). After a system upgrade which included a newer compiler (clang 4) the build produces warnings like this: warning: macro expansion producing 'defined' has undefined behavior [-Wexpansion-to-defined] This is caused by the macro gas/config/aout_gnu.h:USE_EXTENDED_RELOC. Since it is in a header file, the warning triggers for several files. I am unsure what solution is preferable, thus I am suggesting two patches: a) keep the offending macro but define it explicitly to 0 and 1 b) replace the macro usage with its value where it is used. Either patch removes the warning for clang. I did not check with a recent GCC. * gas/config/aout_gnu.h (USE_EXTENDED_RELOC): Explicitly define to 0 and 1. Remove a dangling reference to "AMD 29000" in a comment.
