please update bftpd and make x64 avaible too

[halma]

Hi,

i am using "bftpd" selfcompiled, but i saw it in the repo inside the x86 folder an old version of 4.2 and only avaible for x86... so "tce-ab" wont find it for x64 systems.
Meanwhile bfptd is avaible at Version 5.4 and also runable under x64.

Thanks a lot
