Agreed. I think working around this borkenness in the Makefile is
the best solution; I don't think switching from RTLD_LAZY is good
right now.

It seems that substvar operates on each " " separated token in the
string. The following works for me.

override TCL_SHLIB_LD := $(shell echo $(TCL_SHLIB_LD) | sed 's/-Wl,-soname.*//')

cheers.
