 # make sure to add -Wl,--exclude-libs=libgcc.a to the LOCAL_LDFLAGS for those libraries.  This
 # ensures that symbols that are pulled into those new libraries from libgcc.a are not declared
 # external; if that were the case, then libc would not pull those symbols from libgcc.a as it
 # should, instead relying on the external symbols from the dependent libraries.  That would
 # create an "cloaked" dependency on libgcc.a in libc though the libraries, which is not what
