The error message was in the change-log, included in the patch:

---------
    libbb/lib.a(change_identity.o): In function `change_identity':
    change_identity.c:(.text.change_identity+0x28): undefined reference to `endgrent'
    collect2: ld returned 1 exit status
    make: *** [busybox_unstripped] Error 1
---------

Maybe the problem is in libbb/change_identity.c ?
