Configure test for getpagesize considers only Solaris and thus checks for getpagesize being contained in libucb.
On Linux getagesize is however contained in libc.

The proper fix would be to check for both "in libc?" and if not "in libucb?".

We workaround the problem for Freetz in a hackish way by patching the "in libucb?"-test to "in libc?".
