glibc-2.3 libc_p.a and libpthread_p.a symbol conflicts

[Arthur S Naseef]

Attempting to build a static, profiled executable with libc and libpthread
results in a symbol conflicts on __flockfile, _IO_flockfile, __funlockfile,
and _IO_funlockfile. Below are the specifics of the glibc versions with
sample commands that can be used to detect the problem.

Which library should be defining these? Why do both contain them?
