Great :). I see your bionic-compat.h can handle some errors (e.g. missing
getdtablesize(void)). Since we have already some support, this could be probably
merged (assuming Cyril is not against).
That layer allows you to build more tests than it's currently allowed in our
Makefiles (we filter quite a lot syscalls).

I do build with configure --host triplet add --with-sysroot and SYSROOT
+ add -I and -L flags to sysroot dirs to CFLAGS and LDFLAGS.
But this way autoconf does detect wrongly some options (at least HAVE_PREADV and
BTW which compiler option allows you to ignore missing <string.h> and
