To save space in the recovery partition, modules installed to the
partition are restricted to be built in the first architecure (i.e.,
32bit for 32bit-only device or when TARGET_PREFER_32_BIT is true, and
64bit otherwise).
Most notably, this change removes the 32-bit variant of the linker
(about 1MB). The linker was installed regardless of whether there is a
32-bit executable or not. Now, the unnecessary linker is not installed
and it is guaranteed that all modules in the partition are built with the
same architecture.
Bug: 79146551
Test: m -j
Test: out/target/product/<name>/recovery/root/system/bin/ has only one
variant of the linker.
