Building GCC 4.7.2 on Solaris 10 x86 AMD64 - Getting linker error involving eh_frame

[Jim Rice]

ld: fatal: file .libs/sjlj.o: section [12].eh_frame: section type is SHT_PROGBITS: expected SHT_AMD64_UNWIND

All of my Googling has lead me down the rabbit hole.
Something about binutils?
Am I stumbling in the right direction?
Figured I would ask the source...

Let me know what more info you would like to see if you can help me...

Sun X4100M2 - x86 AMD64 - Solaris 10 U10
Compiling with GCC 3.4.3
GNU ld (GNU Binutils)2.22

solaris-build# mkdir gcc-4.7.2_build
solaris-build# cd gcc-4.7.2_build
solaris-build# $PWD/../gcc-4.7.2/configure --prefix=/opt/gcc-4.7.2 --with-gnu-as --with-as=/usr/sfw/bin/gas \
               --enable-languages=c,c++ CC='gcc -m64'
solaris-build# make

Thanks!
