If there is a specs file, configure.host should use that and only use
-dumpspecs if it is not present.
-dumpspecs dumps the built-in specs, not the ones it finds on the
filesystem.
This can make a difference if specs is hand edited.

So, I think the patch should use ${CC} --print-file-name=specs,
if that prints just specs, it should use ${CC} -dumpspecs,
otherwise cat the specs file.
  specs=`${CC} --print-file-name=specs`
  { if [ x"$specs" = xspecs ]; then ${CC} -dumpspecs; else cat "$specs"; fi; } \
  | egrep ...
