Not really but arm v6+ is an exception here due to reasons explained
earlier. gcc as a target package is a bit
different than rest of them since it has mind of its own when it comes
to configuring it. It encodes certain
defaults into its driver etc. based on the configure parameters.
Ideally when we pass the flags via CFLAGS
it does it for most of packages but not for gcc.
