What is the justification for this? Do you know why io.h was included
before?

Files that use basename(3) should include libgen.h. Why include it
here?

Are you sure that Android NDK headers do not contain this constant?

Why did you include time.h?

We can probably drop the getdtablesize() call completely and use the
CONFIG_ANDROID code on all platforms. I suggest splitting this out into
a separate patch that introduces qemu_getdtablesize() and converts all
callers.

ptsname_r(3) should be used on all Linux hosts because it is reentrant.
This improvement isn't Android-specific, please split it into a separate
patch.
