Builtins are never used unconditionally. Builtin versions are always
checked, and a builtin.mk can do additional checks if necessary (for
optional features or similar things). Besides that, builtin detection
can always be overriden by explicitly setting USE_BUILTIN.* or PREFER.*
variables, either manually or by default in some platform specific .mk
file.
