See glibc_2.10.1.bb:

FILESPATHPKG =. "glibc-2.4:"

So, the answer is that it will use the version from the glibc-2.4
directory.  

I think the semantics of FILESPATHPKG are documented in the manual.  If
they're not, that is an oversight and should indeed be corrected.

You can already do this with a suitable FILESPATHPKG setting, I think.
