plymouth on ppc patch

[Adrian Reber]

To build plymouth (plymouth-0.8.4-0.20101119.2) on ppc I had to create
following patch. Before sending it to the maintainer I wanted to present
it here to make sure it is the correct way to fix it.

PAGE_SIZE seems to be not defined on ppc and following patch fixes
building plymouth:

Is that the correct way to solve it?
