The best I can come up with is checking for the offending string
'libtcl.so.0' in the TCL_SHLIB_LD.

ifneq (,$(findstring libtcl.so.0,$(TCL_SHLIB_LD)))
TCL_SHLIB_LD := $(shell echo '$(TCL_SHLIB_LD)' | sed 's/-Wl,-soname[^ ]*//')
endif

any better ideas out there? I've exhausted my PG time for today ;-)
