argp: Do not override GCC keywords with macros [BZ #16907]
glibc provides fallback definitions already. It is not necessary to suppress warnings for unknown attributes because GCC does this automatically for system headers. This commit does not sync with gnulib because gnulib has started to use _GL_* macros in the header file, which are arguably in the gnulib implementation space and not suitable for an installed glibc header file.
