Ok.  It could be possible to do something with searching the dynamic
linker's data structures to find the end of the data segment for the
executable.  But probably what you should do is put _end in the Versions
script under GLIBC_2.0 so that references in libc like your __minbrk
initializer value will be resolved by the dynamic linker to the program's _end.
