11# a) pull symbols from libgcc.a and b) depend on libdl.so will not rely on libdl.so
12# to provide those symbols, but will instead pull them from libgcc.a.  Specifically,
13# we use this property to make sure libc.so has its own copy of the code from 
14# libgcc.a it uses.

26# with missing symbols. Since this library is just a bunch of stubs, we set
