I suggest updating userspace/toolchain.lkc.
gcc-4.1.2-glibc-2.5-nptl-3 is defined by TOOLCHAIN_ARMEABI_GLIBC1 in
this file.  You can add a TOOLCHAIN_ARMEABI_GLIBC2 and follow the same
layout.  This way you can get an option to choose which you want to
use.

Found a pdf that describes this for imx, but it just replaces the
tool-chain instead of putting in parallel:
