Thanks.
Attached is another small patch for CMakeFindBinutils.cmake. Please apply and
post again the output.
I think what happens is the following:
cmake determines the toolchain prefix and the location correctly
("i686-pc-mingw32-" and "/usr/bin" respectively).
Then it goes into CMakeFindBinutils.cmake to search for ar. But since you have
already set this in your toolchain file, the find_program() call doesn't
search for it (since it is already set).
Since it doesn't search for it, the CMAKE_AR variable doesn't get stored in
the cache, so it is empty later on.
Let's see if we can verify this with the attached patch.
