Use "sed -n …" instead of "sed s/…/p -e d" in s-header-vars

[Olivier Hainque]

Hello,

"sed s/…/p -e d" as used in s-header-vars doesn't work on
at least ia64-hpux, where s/.../p only prints out if -n was
requested as well.

The attached patch fixes this by using '-n' instead of a
trailing '-e d'

We have been using this on all our gcc-4.5 based configurations
for a couple of years now. Bootstrapped and regtested with mainline
on x86_64-linux-gnu.

OK to commit ?

Thanks in advance,

With Kind Regards,

Olivier
