I haven't actually checked, but it safe to assume that if it is not
already a problem it very well could become one (and it probably is).
If the two libutil implementations have functions with the same names
they cannot both be linked into the same binary. A "solution" would
be to use weak linkage, but then you can run into problems when the
functions that share name do not share behaviour (e.g. have different
prototype or return type).

Of course these are personal preferences. There aren't any technical problems
using git submodules assuming you can put everything in the same repo.
