Group needed libraries together to solve the cyclic dependence

between libc, libc_nomalloc and libgcc. When building with upcoming
arm-linux-androideabi toolchain, Symbol raise is needed by libgcc.a
and defined by libc.a or libc_nomalloc.a.which.

This patch groups libgc.a, libc_nomalloc.a and libgcc.a together, which is
a minimal group to solve this problem.
