[petsc-users] Could not find make when building PETSc in Windows 7

[Chetan Jhurani]

I vaguely recall seeing the "could not locate make" error
when a non-cygwin python is picked up first in path.
So ensure that "which python" points to cygwin python.

Another issue is that the --with-make argument, if it is
needed, should be /cygdrive/C/cygwin64/bin (or with some
other drive letter in between where cygwin is installed).
