Using shared libraries, no, you have no way to overload functions.
You can, however, use the non-shared versions of the libraries ---
replace -lsys_s with -lc and any others you might need.

Please note that the memory allocation routines in the NeXT libraries are 
highly optimized and do a good job. Unless there's some other reason to 
override them, it might not be a bad idea to just use the NeXT versions.
(I'm not familiar with the bash code; it might turn out that the 
bash versions of malloc etc do other stuff...)
