Add check for cygwin hosted builds on text mounted filesystems

[Nick Clifton]

Hi Guys,

  I have committed a patch for binutils PR 4334 which adds code to the
  top level configure that detects attempts to run under Cygwin with a
  text mounted filesystem.  As reported in that PR this does not work
  and the check tells the user how to fix this problem if it is
  detected.

Cheers
  Nick
