Yes, I've tested this commit. But it just causes linker errors (as
should be expected):

In function `session_env_getenv_or_default':
~src/guardian/gnupg-for-android/external/gnupg/common/session-env.c:341:
undefined reference to `broken_native_ttyname'

On android we want to avoid the ttyname code all together (presumably
like W32 does?).

In gpgme we the REPLACE_TTYNAME magic from gpgme/m4/gnupg-ttyname.m4
needs to be ported to gnupg as well.
