Jim Patterson 1fd6a4bfc2 Replace which with command for portability (#542)
The `which` command is not part of the posix standard and not available
in some environments.  The `command` command is part of the posix
standard and well supported.

See https://unix.stackexchange.com/q/85249 for a discussion about the
use of `command` instead of `which`.

If a system had `libtool` but not `which`, the build process would issue
an erroneous error stating:

    libtool is required, but wasn't found on this system

Switching to `command` corrects this problem.
