Mat Martineau bf82c69f10 build: Undef _FORTIFY_SOURCE for unoptimized builds
'./configure --disable-optimization --enable-maintainer-mode' would
result in build errors. _FORTIFY_SOURCE requires that optimization is
enabled and issues a compile-time warning which is treated as an
error. Disabling optimization takes precedence over fortification in
this case, since it is being explicitly requested.
