Use SC_PROG_TCLSH to set a native tclsh in the Makefile.

When installing the libraries a native tcl interpreter is used to
process some files. The makefile uses NATIVE_TCLSH for this. This patch
causes us to prefer an installed tclsh over the build product which solves
build issues when cross-compiling (provided a native tcl is installed).
If there is no native version, just try using the build product.
