Back to this one...

I think we're hung up on this part:

This is still wrong because it depends on information that Tcl generated
during its build using its compiler and linker configuration.

Also, if you use GCC to link, specifying -lc is almost certainly wrong in
any case.

I think what should work is this: Assign

SHLIB_LINK = $(TCL_LIB_SPEC) $(TCL_LIBS)

unconditionally. If the port doesn't like mention of shared lib
dependencies, it should ignore SHLIB_LINK in Makefile.shlib. If the port
wants to have -lc, it should add it to SHLIB_LINK in Makefile.shlib.
