Hi, Carlos. Thanks for your quick response. Yes, it does work as
expected when I use the newly built loader with the newly built glibc.
I can't unfortunately replace the system's default loader in /lib, and
there's no environment variable equivalent of `LD_LIBRARY_PATH` that I
know of to set the default loader.

Is it possible to build glibc 2.19 with an OS/ABI of UNIX - System V?
If not, is there a component of my toolchain (Linux headers, binutils,
glibc) that I can downgrade to an earlier release that will build a
UNIX - System V glibc?

Thanks,
Shaun
