ANDROID: kbuild: lto: permit the use of .a archives in LTO modules

Browse Source 
Permit the use of AR archives in .a format as input to the partial link
that produces a kernel module. This permits a set of builtin objects to
be bundled with a module object, to create a single module carrying the
payload of several modules. This is used by the FIPS 140 module.
