That is a possibility, but we recommend against doing that where posible
in Mingw RPM builds and cannot do it by default, because a number of
programs need to be able to use both the native & mingw versions of 'ar'
in their configure script. eg, they use native toolchain to build a
helper program, that they then use in their build process. So we can't
simply point 'ar' to the mingw version. In autotool'd apps configure
will generally do the right thing & find i6868-pc-mingw32-ae, for other
apps, having a makefile variable AR=ar will at least allow for easy
override when doing a mingw build by adding AR=i686-pc-mingw32-ar to
the make flags.
