Search-and-replace (on ", ") is your friend.  Here's an edited version 
that took me a minute or so.  :)

   capability: <code>acos</code>, <code>acosh</code>, <code>asin</code>,
   <code>asinh</code>, <code>atan</code>, <code>atan2</code>,
   <code>atanh</code>, <code>cbrt</code>, <code>cos</code>,
   <code>cosh</code>, <code>erf</code>, <code>erfc</code>,
   <code>exp</code>, <code>exp10</code>, <code>exp2</code>,
   <code>expm1</code>, <code>fma</code>, <code>fmax</code>,
   <code>fmin</code>, <code>hypot</code>, <code>log</code>,
   <code>log10</code>, <code>log1p</code>, <code>log2</code>,
   <code>pow</code>, <code>pow10</code>, <code>sin</code>,
   <code>sincos</code>, <code>sinh</code>, <code>tan</code>,
   <code>tanh</code> and <code>tgamma</code>.  The <code>float</code>
   and <code>long double</code> variants of these functions (e.g.
   <code>sinf</code> and <code>sinl</code>) are also handled.  (The
   <code>sqrt</code> and related functions were already optimized in
   prior GCC releases.)  </li>
