Well as far as I remeber the attached patch wasn't complete and it was
more of a hack than anything else.

On the other hand I'm not against having LTP ported to Android. If the
changes comes to us in reasonable small chunks that could be reviewed, I
would be happy to help and possibly merge them into the upstream
codebase.

Sorry that I couldn't help more here. I don't have any expirience with
Android SDK and I do not intend to play with it in the near future.

That seems to be way better than the Android.mk mess. And it would
certainly be great to have Android HOWTO document bundled with ltp
sources.

The patch seems to be relatively small. Is this all that is necessary to
build LTP on Android? Have build the open posix testsuite?

Looking at the patch itself. The ifdef 0 shouldn't be there, the
!defined(_ANDROID) is better. The FILTER_OUT_DIRS should be either
triggered by Android environment or the testcases should be fixed.

The GLIBC_PREREQ() in the accept4_01 should be moved to configure
script.

The GLIBC_PREREQ() from tst_tmpdir() is about to be removed. Hm and why
is that defined to 0? The uclibc implements mkdtemp() or not?

Well I can't do much for Busybox but I could help to fix LTP to build on
Android ;).
