Keep the symbol table in the shared libc.
In order to allow the unwinder code to have meaningful names for
libc functions, leave the symbol table. This results in the libc.so
getting to be about ~130K larger on all arm platforms and about ~70K
larger on mips/x86 platforms.

# WARNING: The only library libc.so should depend on is libdl.so! If you add other libraries,
# make sure to add -Wl,--exclude-libs=libgcc.a to the LOCAL_LDFLAGS for those libraries. This
