AFAICS you make resonable effort to detect if filesystem
containing /bin/sh is case-sensitive. In many cases
this is the same filesysytem as build tree, but in many
cases this is distinct filesystem. IMO we should check
directly build tree. Just create file there and check
if it can be accessed using different case.

Useful: yes to some degree. However ATM gain seem to be
to small compared to the effort. I hope that problem
will go away when we improve our build system (in particular
I would like to avoid splitting .spad files into pieces
which is responsible for current problem).
