[Otavio Salvador]

+1 :-) very cool :-D

> * python support is needed for providing finer scripting control
> in gdb, and for remote controling gdb for example from qtcreator
> * gdb/configure tries to autodetect python using python executable
> with --includes --ldflags --exec-prefix to get the right flags
> As it's difficult to achieve in OE's context, we generate a
> script which will return the right values and make gdb's build
> system happy. This idea was taken from the following article :

> * tested using angstrom & armv7/armv5 targets & qtcreator 201005 & 2.4.0
