I am now playing with arm-v7a-linux-gnueabihf (although I initially
used OSELAS toolchain 2013.12.2) and can confirm that this works fine
so far. This is without any changes or patches to the standard
toolchain configuration.

Can you provide some additional detail on why this had to be disabled?
The arm-v7a-linux-gnueabihf toolchain also has "cortex-strings" in
PTXCONF_GLIBC_EXTRA_ADDONS and so far it seems to work fine (although
I have only been able to do limited testing)
