No; Auxiliary means that there are a set of interfaces which have basic (read: slow) versions in /lib/libc.so.1, and platform-specific (read: fast) versions in /plaform/.../libc_psr.so.1. Since there are versions in libc, the auxiliary filter library is optional, and you can turn off all aux filters by setting LD_NOAUXFLTR=1 (see ld.so.1(1) for all other possible environment variables)
