Patch: Override auto-guessed max cmd line length in MingW

[Mohan Embar]

Hi Patch Folks,

This patch is another piece needed for a self-hosted
build of GCC/GCJ 3.3 under MingW GCC 3.2. For some reason,
the maximum command line length guessed by ltconfig for MSYS
(the Win32 bash shell port) on Win32 is almost 400K, which
is way too much for ar to handle. This overrides the
auto-guessed value to 30000, a number Ranjit previously
came up with.

Is this the correct way to do this?

Enjoy.
