This change should not be necessary.

Please instead replace all occurrences of getdtablesize with
qemu_getdtablesize.

Please replace this with

#include <libgen.h>

#ifndef IOV_MAX
#define IOV_MAX 1024
#endif

and get rid of os-android.h.

Better:

    #if defined(CONFIG_ANDROID)
        char slave[PATH_MAX];
    #else
        const char *slave;
    #endif

    ...

    #if defined(CONFIG_ANDROID)
        if (ptsname_r(mfd, slave, PATH_MAX) < 0)
            goto err;
    #else
        if ((slave = ptsname(mfd)) == NULL)
            goto err;
    #endif
