cmake: Set GCC min-pagesize parameter to 0

Browse source 
GCC 11 and above may generate a warning when dereferencing a constant
address pointer whose address is below the value specified by the
`min-pagesize` parameter.

This commit sets the `min-pagesize` parameter to 0 such that GCC never
generates the warnings for any constant address pointers.

For more details, refer to the GCC PR99578.
