[Bug 869966] [NEW] gcc-4.5 fails to cross-build

[Wookey]

Public bug reported:

Crossbuilding gcc-4.5-base using xdeb in a natty chroot fails.

The build command is:
xdeb --only-explicit -a armel --prefer-apt --apt-source --debug --force-rebuild gcc-4.5
using xdeb 0.6.5~crosstoolsppa from https://launchpad.net/~linaro-foundations/+archive/cross-build-tools

The actual build command xdeb issues is:
debuild --no-lintian -eUSER -eCONFIG_SITE=/etc/dpkg-cross/cross-config.armel -eDEB_BUILD_OPTIONS=nocheck -eGTEST_INCLUDEDIR=/usr/arm-linux-gnueabi/include -eGTEST_LIBDIR=/usr/arm-linux-gnueabi/lib -ePKG_CONFIG_LIBDIR=/usr/arm-linux-gnueabi/lib/pkgconfig:/usr/arm-linux-gnueabi/share/pkgconfig:/usr/share/pkgconfig -eDH_VERBOSE=1 -aarmel -b -uc -us -tc

The final erorr is:

gcc -c -DIN_GCC    -DGENERATOR_FILE -I. -Ibuild -I../../src/gcc -I../../src/gcc/build -I../../src/gcc/../include -I../../s$
                -o build/genmddeps.o ../../src/gcc/genmddeps.c
