Comment:
`XBPS_CROSS_BASE` will not work since the libc is not installed for crossbuilds (it's shipped by crosstoolchains)

I'm not fundamentally opposed to using fortify, the library could use cleaning up (it'd simplify it too, e.g. use `__builtin___memcpy_chk` and so on) and the way you implemented it in the PR is questionable

if we're to add this, the best opportunity is when doing the gcc10 transition
