(test): On Android, use "/proc" instead of "/".
(main): Determine the relative location of the 'pwd' program
accordingly.
* modules/posix_spawn_file_actions_addfchdir-tests (Depends-on): Add
xvasprintf.
* m4/gnulib-common.m4 (gl_CONDITIONAL): New macro.
(gl_CONDITIONAL_HEADER): Use it instead of AM_CONDITIONAL.
* m4/libgmp.m4 (gl_LIBGMP): Likewise.
* modules/posix_spawn_file_actions_addfchdir-tests (configure.ac):
Likewise.

(is_qemu): New variable.
(test): Under QEMU user-mode, don't expect that "pwd" produces the
result "/".

name test.

"bin/pwd".
