Replace getpagesize(), remove #include <asm/page.h>

The pagesize.patch for libsdl() replaces PAGE_SIZE (which is good), but leaves
in the include for asm/page.h.  Also, it replaces PAGE_SIZE with getpagesize(),
which is removed in POSIX.1-2001, and works incorrectly on some older glibc's
(see getpagesize man page for details).

This patch replaces getpagesize() with sysconf(_SC_PAGESIZE), and removes the
include for asm/page.h

Noticed this issue when I tried to build libsdl for a "native" system, which
doesn't install kernel headers.
