One target file (config/c6x/t-elf) lists _printf and _gcc_bcmp in
LIB2FUNCS_EXCLUDE, but that does not have any effect, since those are
not filtered away from LIB2FUNCS_ST. Another option is to do as in
config/rl78/t-rl78, which explicitly sets LIB2FUNCS_ST
# Remove __gcc_bcmp from LIB2FUNCS_ST
LIB2FUNCS_ST = _eprintf
but honouring LIB2FUNCS_EXCLUDE also for LIB2FUNCS_ST seems more
natural.

* Makefile.in: Filter out LIB2FUNCS_EXCLUDE from LIB2FUNCS_ST.
---
AFAICT, this will only affect the c6x port, to do what I assume was
always intended, but I don't have a way of testing that. My only
motivation for this is that I have an out-of-tree VxWorks patch that is
more natural on top of this.
