Linking problem when building gcc 4.6.2 on Ubuntu 10.11 (Oneiric)

Hi all,

I'm trying to build gcc 4.6.2 (checked out from the 4.6.2 release
branch in Subversion)  on 64-bit Ubuntu 10.11 (Oneiric Ocelot) using
gcc 4.6.1.  My problem is that configuration and compilation work
fine, but linking fails when ld can't find crti.o:

/usr/bin/ld: cannot find crti.o: No such file or directory
collect2: ld returned 1 exit status
make[3]: *** [] Error 1

The entire toolchain was installed via the package manager and all the
required dev libraries are installed, including libc6-dev.  I'm not
building in the source directory.  The distro was updated to 10.11
from 10.4 (Natty Narwhal) if that makes a difference.  The only
configuration flag that I have set is --prefix.

Any ideas why this would fail?  I clearly have the devel libraries
(and crti.o) installed so it's odd that the linker can't find them.  I
know 10.11 added --as-needed as a default gcc flag, but it seems odd
that gcc itself would have issues building under that.  I've enclosed
the last 15 lines of my make output below and I can send any
configure/make output that would be helpful.

Here's where find says my libraries lurk:
