I tested that Ok, as Android defines PATH correctly. However, I have found these comments on a systemtap execvp call so I am no sure of possible interferences with other requirements:
/* Note that execvp() is not a direct system call; it does a $PATH
search in glibc. We would like to filter out these dummy syscalls
from the utrace events seen by scripts.
This filtering would be done for us for free, if we used ptrace
... but see PR6964. XXX: Instead, we could open-code the
$PATH search here; put the pause() afterward; and run a direct
execve instead of execvp(). */
