[yocto] [meta-mingw][PATCH 3/9][master][jethro] toolchain-scripts-mingw32: Use short paths (8.3)

[Mark Hatle]

When using standard paths, the user may end up exceeding the path length to
some toolchain helper libraries (DLLs) and binaries.

By switching to using the "short path", we can avoid this in many more cases.

If the user does exceed the path length, their only option will be to move
the SDK lower in their directory tree.
