[Cbe-oss-dev] [PATCH 1/7 v2]MARS/core: Fix host static lib

[Yuji Mano]

This fixes the problem where mars_kernel_entry symbol is undefined in the static
library libmars.a. The problem is the MARS kernel spu embedded object does not
get properly included in the static library.

This is a hack so that we can have the MARS kernel embedded spu object included
into the static library. The hack forces creation of the .lo object file usually
created by libtool. Without the hack there does not seem to be any clean
solution for having automake and libtool to create a libtool object from an
object file created by some external application such as ppu-embedspu.
