Add -Bsymbolic to the ld flags when linking the dynamic linker.

We don't need this on architectures other than aarch64, and
we're still investigating why we need it on aarch64, but it
doesn't seem unreasonable to have this flag set when linking
the dynamic linker anyway; it's clearly the intended behavior.

Make it possible for code to query the dynamic linker's default search path.

We're not going to have init(1) set LD_LIBRARY_PATH globally on 64-bit.
This patch makes it possible for libnativehelper to set LD_LIBRARY_PATH
in each Java VM (to support System.loadLibrary) without also hard-coding
the default search path there.
