FAQ link to crossgcc broken

[R. Diez]

Hallo all:

I wanted  to point out that, on this page:

  https://sourceware.org/newlib/faq.html

under question 3:

  I want to have newlib built with gcc and other components
  from the net. How do I do this?

the following link is broken:

  http://sthoward.dyndns.org/CrossGCC/

This is important because many Newlib users have to build their own cross-compilation toolchain.

Best regards,
  rdiez
