It was recommended to me on binutils@ that the top-level configure check
should fail if --with-debuginfod is given but not installed.

Despite that I can remove the top-level AC_DEBUGINFOD to match the
behavior of other configure options.

gdb.texinfo was updated in this patch but not README, will fix that.
