[Tutor] Explicitly define the lib path for python during build time

[Tony Wang]

Hi there,

I'm building python2.7 from src code. Usually, after make, if I define
a user folder to install the python, the python will depends on the
lib folder in the installer folder.

But my needs is quite special here, I need to statically link python
with gdb, and I hope the python in gdb I build can run on other PC. I
know that I can do some tricky thing to include the python .py lib
file inside gdb folder, but I prefer to depends on user PC's native
python library.

So I need to add the /usr/lib/python2.7 or something like that to the
python lib search path. I know that I can ask user to do export
PYTHONHOME, but is there any way to explicitly define more than one
lib search path during build time?

BR,
Tony
