[Samba] Building from source on an ARM71 based router

[Zac Morris]

​No, sorry, it's actually failing on "configure" which this script calls. I
should have been more clear.

./configured is failing at step: ​*Checking uname sysname type*

It's obviously missing some app/header/library, but reading through all the
breakpoints listed in the error (re-pasted below) I can't make out from the
code what it's looking for, and the config.log doesn't show a better error.
I even manually ran the last step shown in config.log and it ran fine, so I
don't believe that is the step that it's actually hanging on. I'm hoping to
hear back from someone that's familiar what's actually happening during
this step of configure.

*Checking uname sysname type*              : Traceback (most recent call
last):
