You have to link statically because the onboard library and the cross library are not the same: you can't use the onboard dynamic libraries.

Finding that odd, I dug a bit more and the figured that the system is based on GCC 3.4.6 which, incidentally, is the version used to build busybox/initrd.

Hi David.
I think you are using the wrong toolchain for the TS7500 series. I use the version you list for the TS7250, and because I want the same executable to run on both TS7250 and T7550, I got the problem of wrong C++ library.
It does look strange that the path
/ts-arm-sc/ts-7500-linux/cross-toolchains provides the wrong version, but you get to love TS's little quirks after a few years. Honestly.
I copied the libstdc++.so.5 from a TS7250 to the TS7550 and everything is fine.
The crosstool-linuc-arm-uclibc-3.4.6 is used to build the fastboot environment which means that executables provided there (like nandctl) cannot be run in the Debian environment.
I've had a quick poke around on the FTP site and can't find anything I would recommend to you.
