Remove unnecessary parentheses in declarations

Remove unnecessary parentheses in declarations

GCC commit a94975e57 ("C++ warning on vexing parse") introduces new
warnings "unnecessary parentheses in the declaration of ...".  These
cause the build of binutils and gdb to fail.  This patch removes those
parentheses for a successful build.
