Bug#676421: gcc-4.7: cross-compiler wants /usr/$triplet/include/ instead of /usr/include/$triplet/

[Adam Borowski <kilobyte@angband.pl>]

Package: gcc-4.7
Version: 4.7.0-11
Severity: normal

Hi!

Building a cross-compiler fails with:
.-====
The directory that should contain system headers does not exist:
  /usr/arm-linux-gnueabi/include
`-====

And here's the cause:
[~]$ dpkg -L libc6-dev:armel|grep arm-linux-gnueabi|head -n1
/usr/lib/arm-linux-gnueabi
[~]$ schroot -c squeeze-cross
squeeze-cross:[~]$ dpkg -L libc6-dev-armel-cross|grep arm-linux-gnueabi|head -n2
/usr/arm-linux-gnueabi
/usr/arm-linux-gnueabi/include

Non-cross builds correctly look in /usr/include/$triplet/, so I'm afraid
cross ones need to be adjusted.
