r156315 - /trunk/config/mh-mingw

[Kai Tietz]

Hi,

this patch seems to be escaped, as obvious the check-in comment
doesn't fit at all to the done modification.
The change (and I thought I have it only in my local tree) adds the
undefined option for linker, which is for PE-COFF default.
If this change produces any issues (I am not aware of any until now)
I'll remove it, but I would like to hear Danny's and Dave's opinion
about this target option.

Kai
