For GDB sometimes the hello binary is located in /home/devel/work and sometimes
in /home/devel/jan. Unify it.

embedded-devel: remove unnecessary "cut" in command2019-02-28T14:41:20ZJohn Ognessjohn.ogness@linutronix.de2019-02-28T14:41:20Zurn:sha1:e832bf82cfd98a477867f71394fd933c59d02556
The -dM argument shows the built-in macros. Cutting the #define
from the output not only make the command unnecessarily complex,
but also works against illustrating that they are macros.

app/debugging: add address sanitizer example2019-02-28T10:58:44ZKurt Kanzenbachkurt@linutronix.de2019-02-28T10:10:23Zurn:sha1:fd7e64b0a1ee69ddf608ed0f5ad4867f0f5277d8
The address sanitizer is a useful tool for debugging lots of memory related bugs
such as heap/stack overflows, user after frees and much more.

profiling - gprof: use no PIE compiler and linker option2019-01-28T18:54:26ZManuel Trautmanut@linutronix.de2019-01-14T20:24:35Zurn:sha1:35cff9185b355d7a471b5164b2235409e584dbfb
PIE is enabled in the gcc of Debian/stretch by default.
However the gprof in stretch isn't able to produce any
output if PIE is enabled. This is also documented here:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=854704
Disable PIE for the moment to get some gprof output.
However i'm not able to find out how to disable PIE if
compiling and linking is done in two steps. Therefore this
is just removed.
