Never mind, compiling without the LTO option didn't help.

I had the following libmap.conf entries:
libgcc_s.so.1   gcc45/libgcc_s.so.1
libgomp.so.1    gcc45/libgomp.so.1
libobjc.so.3    gcc45/libobjc.so.2
libssp.so.0     gcc45/libssp.so.0
libstdc++.so.6  gcc45/libstdc++.so.6

I commented all of those out, went into /lib and /usr/lib and moved the 
base versions of the libraries out of the way, ran ldconfig -R, made 
sure that /usr/local/lib/gcc45/libssp.so.0 is the only ssp library, and 
then tried again, same error. The symbol appears to be in the lib:

nm libssp.so.0 | grep __stack_chk_fail_local
00000ac0 t __stack_chk_fail_local

So I'm at a loss, and pretty close to throwing in the towel and going 
back to the base gcc for everything.
