Add bionic mount points under /bionic This change adds following files and symlinks: Files: /bionic/lib[64]/lib{c|dl|m}.so /bionic/bin/linker[64] Symlinks: /system/lib[64]/lib{c|dl|m}.so -> /bionic/lib[64]/lib{c|dl|m}.so /system/bin/linker[64] -> /bionic/bin/linker[64] /system/bin/linker_asan[64] -> /bionic/bin/linker[64] The files serve as mount points for either the bootstrap Bionic or the default Bionic from the runtime APEX. init does the bind-mounting during booting. The symlinks are there to not change the ordinary paths to the bionic files; there are many places that the paths are implied or hard-coded, e.g., dlopen("/system/lib/libc.so") or DT_INTERP pointing to /system/bin/linker in the vendor prebuilts. Bug: 120266448 Test: m blueline, cf_x86, aosp_arm The aforementioned files and symlinks are found Change-Id: I97e38c29409ac0610dde285db8df6e94a7930094

This file serves as a mount point for bionic files either from /system partition or from /apex/com.android.runtime. This file is never meant to be accessed directly.
