See build/soong/README.md for more information.
gen.mk is currently using build system internals in order to tell the
gen_*.sh scripts how to call the compiler. Soong genrules do not provide
the required information to call a compiler, so use a `cc_object {}` to
do the preprocessing steps, and pass the output from that into the
gen_*.sh scripts (cc_genrule).
It fixes the missing dependencies for the 2nd arch, and uses the correct
libc headers for the _vendor variant.
