Tom Tromey d706b69e48 Do not adjust mtime timezone on Windows
PR win32/25302 notes that gdb will crash when trying to "run" even a
simple program on Windows.  The essential bug here is that the BFD
cache can easily be corrupted -- I have sent a separate patch for
that.

The particular reason that the cache is corrupted on Windows is that
gnulib overrides "stat" to make it do timezone adjustment -- but BFD
does not use this version of stat.  The difference here triggers the
latent cache bug, but can also cause other bugs as well; in particular
it can cause spurious warnings about source files being newer.

This patch simply removes the stat override on mingw, making gnulib
and BFD agree.

I tested this by backing out the local AdaCore changes to work around
this bug and then verifying that I could reproduce it.  Then, I
applied this patch and verified that "run" works again.
