libtool vs purify?

[Charles Randall]

Purify requires you to prefix the "purify" command in the final link. For
example,

        gcc -c file-a.c
        gcc -c file-b.c
        purify gcc file-a.o file-b.o

With 1.3.x, I'd simply hand-edit src/Makefile to achieve this. How can I
either get libtool to invoke purify or hack the files by hand to accomplish
this?
