Because libtool is a stand-alone shell script, not something that is
necessarily part of a Makefile rule.

I prefer ${PWDCMD-pwd} in shell scripts.  Having Makefile
substitutions would just require the user to set PWDCMD earlier,
requiring reconfiguration in case s/he didn't realize earlier that it
was necessary.

I could go with `PWDCMD = $${PWDCMD-pwd}' in Makefiles, though.
