[OE-core] [PATCH 01/17] toolchain-scripts.bbclass:add PYTHONHOME variable to environment-setup

[Hongxu Jia]

When relocating the SDK, applications using python will search for
python modules in the default location and will fail to start.
The below errors are thrown by gdb, for example:

Could not find platform independent libraries <prefix>
Could not find platform dependent libraries <exec_prefix>
Consider setting $PYTHONHOME to <prefix>[:<exec_prefix>]
ImportError: No module named site

In order to overcome this, add the PYTHONHOME variable to the
environment-setup script for both standalone toolchain and
adt-installer. No need to do that for meta-ide-support environment
script since this toolchain does not get relocated.

Cherry-pick commit db0a02492c2a53c1917b753bcf21c4ee7c0ecf59
