[Xotcl] potential problem in makefile for solaris fixed

[Gustaf Neumann]

Hi everybody,

Andreas Kupries found a small problem with the makefile on solaris.

> The Makefile target "install-shells" (around line 421)

> I have to use 'test -f', or the installation of xotcl fails.

This is the same code as in prior versions, so it won't effect many
people. I have fixed the tar file on www.xotcl.org without upgrading
the version number.

best regards
