Maybe add a comment that this needs adjustment?

I expect that there is probably similar bit rot within the NaCl port 
elsewhere.

They still ship a NaCl SDK for Chrome, but it's Clang-based now, so it 
can't be used to compile glibc.  The NaCl GCC port has never been 
upstreamed.  There are patches somewhere for GCC versions otherwise 
supported to build glibc (late GCC 4.x versions), but if we probably 
should move to GCC 5 as a minimum version soon (because the 4.x branches 
are all dead upstream), and then there wouldn't be a NaCl GCC left.
