This is fairly harmless, but note that it could be harmful to add
-Wl,-soname=xxx with different values of xxx. In particular, if the
soname is not of the form "libc.*", the dynamic linker will attempt to
load it (not knowing it's libc) and very bad things will happen when
libc is loaded twice in the same process.
