where it reads

+      <a href="https://gcc.gnu.org/install/specific.html#nvptx-x-none">
+      <code>--with-arch=</code></a> flag; if not specified, GCC defaults to
+      <code>sm_30</code>. GCC's target libraries are build both with
+      <code>sm_30</code> and the specified target architecture.

I suggest "configure option" instead of "flag" (if that's it, of course). 
 
And I'd start the following as a full sentence "If not specified", or in 
fact omit it, since "GCC defaults" already implies "If not specified"?

"are build" -> "are then built", and switch the last two sentences?

Okay with those changes (or telling me I'm wrong ;-).
