Portability problem in rtems custom cfg's

[sotko at isr.com (David Sotkowitz)]

In the cfg sources, SED is used to remove CR-LF,and leave a LF on Unix.
The problem is, on NT, where the removal is unnecessary, a nibble is
removed from the checksum at the end of the srecord when generating the exe.

The bug is in RTEMS 4.0.0

The following diff provides a modification that will work. Alternately,
one could conditionalize on ostype.
