OK, I've looked into the situation - looks simple enough to fix: just
tweaking the logic so we only enable apr_os_uuid_get if we find both a
linkable function and a header.

I've found that the patch that started this thread and committed in
r355780 actually doesn't work - the build still dies, because it tries
to use compile code using one uuid implementation using the header of
the other - I'll fix this.

I have one question: if *both* uuid implemenations are available, which
one should we prefer? The options are:

DCE/BSD <uuid.h> uuid_create() libc
e2fsprogs <uuid/uuid.h> uuid_generate() libuuid

I'm inclined to prefer the one in libc, in order to minimize dependencies.
