Recently Tcl's configure machinery was revised to stop
seeking out and linking to a libieee.a library, since
support for them is going away.  This was a change to
the SC_TCL_LINK_LIBS in Tcl's tcl.m4 file.

The corresponding change for TEA is probably a good idea too.

It's not clear how important this is, because I do not have
a sense of how much TEA_TCL_LINK_LIBS is used.

For example, none of the TEA-using packages that are bundled
in source code form with Tcl releases make use of it.
