This may be a little drastic, and I haven't tried it, but couldn't you do 
this?
1) copy your libc.a file to a "safe" directory for later (when everything 
falls apart :-). 
2) use ar to remove the offending function from libc.a.
3) compile and link with the "emasculated" libc.a.

This would have the added benefit that, if you replaced, say, malloc(), 
all other library functions that use malloc() would also use your "new, 
improved" malloc.
Alternatively, you could copy libc.a to your working directory, remove 
the offending functions, and modify the linker's search path putting your 
working directory first.
