Arch Linux

The deb referenced in the PKGBUILD is gone. There is a newer one:
http://archive.ubuntu.com/ubuntu/pool/universe/g/gcc-4.7-armhf-cross/cpp-4.7-arm-linux-gnueabihf_4.7.3-1ubuntu1cross1.81_amd64.deb

Since upgrading to the 4.7.2-2 version last week (along with upgrading gcc-arm-linux-gnueabihf-bin to 4.7.2-2 and binutils-arm-linux-gnueabihf-bin to 2.23.2-1), I can't compile linux kernel sources from kernel.org Torvalds' repository configured for armv7 multi-platform target. Before upgrade I've been building it regularly without problems. I've even tried reverting to the specific version I'm absolutely sure I have compiled successfully just a week or so before the upgrade.

Here's the simplest way to reproduce:
$ git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git linux-torvalds
$ cd linux-torvalds
$ export ARCH=arm
$ export CROSS_COMPILE=arm-linux-gnueabihf-
$ make make multi_v7_defconfig
$ make
scripts/kconfig/conf --silentoldconfig Kconfig

...

The output contains thousands more error lines, mostly 'unknown type name' and 'dereferencing pointer to incomplete type'. Looks like some missing/incomplete headers in the toolchain, or some conflict between header files from toolchain and from the built kernel source itself... Any ideas what may cause this?
