[ast-developers] grep and xargs fail to build in "package test"

[Terrence J. Doyle]

When I run "package test" for ast-open-2014-09-29, I still see a
couple of places where
test programs won't link because of undefined symbols:

$ package test

The test suite is trying to build grep and xargs as standalone
executables. This can be done with grep by compiling with -DSTANDALONE,
but there's no way to do this with xargs. What's more, both need to be
linked with -lcmd to define __cmd_init.

But, then I see where "package make" has already built grep.o and
xargs.o and put them in libkshcmdtst:

$ package make

Should the test suite be trying to rebuild what's already been
built? If so, shouldn't it be applying the same compile and link options
and libraries?
