[PATCH] JOBS: fix klibc DEBUG compilation

[maximilian attems <max@stro.at>]

dash didn't compile in DEBUG mode against klibc for all long time.
Now it fails at link stage for not having setlinebuf(3).

Fixes:

usr/dash/show.o: In function `opentrace':
show.c:(.text+0x86): undefined reference to `setlinebuf'                        
Signed-off-by: maximilian attems <max@stro.at>
---

the last open error, looks more like a klibc bug to me,
will fix it there:
show.c:(.text+0x36): undefined reference to `freopen'
