No, this is a regular dpkg-buildpackage of the "gcc-4.6" source package:
$ apt-get source gcc-4.6=4.6.1-13
$ cd gcc-4.6-4.6.1
$ dpkg-buildpackage -us -uc -b
My /usr/include/asm is just a leftover empty directory. If I run:
$ dpkg -L linux-libc-dev
$ dpkg-deb -c /var/cache/apt/archives/linux-libc-dev_3.0.0-3_amd64.deb
I can see files in the following places, which matches up with what I
actually see in those directories:
/usr/include/asm-generic/*.h
/usr/include/linux/*.h
/usr/include/linux/*/*.h
/usr/include/mtd/*.h
/usr/include/rdma/*.h
/usr/include/sound/*.h
/usr/include/video/*.h
/usr/include/xen/*.h
/usr/include/x86_64-linux-gnu/asm/*.h
My currently installed GCC compiler packages are:
gcc 4:4.6.1-2 (gcc-defaults 1.107)
gcc-4.6 4.6.1-13
If I run this command on my regular system compiler:
$ cpp -v </dev/null
[...]
#include <...> search starts here:
/usr/lib/gcc/x86_64-linux-gnu/4.6.1/include
/usr/local/include
/usr/lib/gcc/x86_64-linux-gnu/4.6.1/include-fixed
/usr/include/x86_64-linux-gnu
/usr/include
End of search list.
[...]
So it looks like everything is OK. But when I try the build listed at
the beginning of this email, the very first "xgcc" partway through the
bootstrap fails with the attached message (with libgcc).
If I manually extract the command-line from that, strip out the object
files, and add the options "-E -Wp,-v -x c /dev/null", I get the
output found in the second attachment. The highlights are below:
#include "..." search starts here:

The /usr/include/x86_64-include-linux directory with some headers
from linux-libc-dev is distinctly missing from that search path.
