Excessive link time with 2.16.1

I'm trying to upgrade from binutils to 2.16.1.  However,
my link time goes up from 12 seconds to 15 minutes!  The link time
increase seems to be peculiar to one application - other link times
don't seem unusual at all.

I'm building a Linux cross compiler.  I'm using gcc-4.1.1.

For the build machine:
[dmlee@hermes ~]$ uname -a
Linux 2.6.16-1.2115_FC4smp #1 SMP Mon Jun
5 15:01:20 EDT 2006 x86_64 x86_64 x86_64 GNU/Linux

I configure both versions the same way:
CFLAGS="-O2" $(BINUTILS_PATH)/configure \
        --target=i686-linux \
        --prefix=$(INSTALL_PATH) \
        --libdir=$(INSTALL_PATH)/host-lib \
        --enable-64-bit-bfd \
        --disable-nls \

I configure gcc using:
CFLAGS="-O2" CXXFLAGS="-O2" $(GCC_PATH)/configure \
                --target=i686-linux \
                --prefix=$(INSTALL_PATH) \
                --with-headers=$(INSTALL_PATH)/i686-linux/include \
                --disable-nls \
                --enable-symvers=gnu \
                --enable-threads=posix \
                --enable-__cxa_atexit \
                --enable-languages=c,c++ \
                --enable-clocale=gnu \
                --with-local-prefix=$(INSTALL_PATH)/i686-linux \
                --disable-multilib \
                --enable-debug \

The app in question is C++ compiled with CXXFLAGS="-O3 -ggdb".

I did a quick run with Oprofile - most of the time is spent in mempcpy.
I've not been able to get much more information through profiling.
