Error about libcrypt when compile on fedora21

[zhengyazhou]

Hi,
I accept advice of Gedare<gedare at rtems.org> and I build a crossing compile environment on my computer using a virtual machine with a fedora21 host.Then I get the source code of rtems though git clone git://git.rtems.org/rtems.git
But I meet another problem of libcrypt when I execute the command 'make all install' after configure.
Bellowed is the detailed error:

Making all in libcrypt

I fond Libcrypt is lib function written in C ,and I didn't change anything about it,Is my compile environment problem ?
I need some support,what's your viewpoint about this error? How can I fix this bug?

Best wishes
Asher
