我试图交叉编译此处找到的ntfs-3g软件包：http://tuxera.com/opensource/ntfs-3g_ntfsprogs-2014.2.15.tgz
但似乎无法正确交叉编译它，我的Fedora相当新，所以arm binutils是arm-linux-gnu。
./configure CC=arm-linux-gnu-gcc --build=arm-linux-gnu --with-gnu-ld --prefix=/usr/bin/arm-linux-gnu-
But just end up with:
[root@localhost ntfs-3g_ntfsprogs-2014.2.15]# ./configure CC=arm-linux-gnu-gcc --build=arm-linux-gnu --with-gnu-ld --prefix=/usr/bin/arm-linux-gnu-

所以我做得更远但不是我的。即使这些函数是在pwd.h中定义的，但grp.h编译仍然失败。
