[工作點滴] Busybox 1.7.2 taskset.c編譯產生error

在編譯busybox時，我用預設的config，即
#make defconfig
然後再用某toolchain，
#make ARCH=arm CROSS_COMPILE=arm-linux-
編譯之後會產生兩個狀況的error，此為其一，另一個為route，
但我尚未找到解決方法，暫時將其disable就可以編譯過，
而這個taskset.c我在網路上找到如下一篇文章，
主要的問題是產生在sched_getaffinity與sched_setaffinity
這兩個函式的參數個數，
busybox主要為uclibc所設計，而在glibc底下剛好就發生了這個mismatch，
而編譯的狀況跟source code修改如下，如此即可順利編譯成功！

Something like this should work, unless there is a more elegant way:
