New submission from Xavier de Gaye:
When cross-compiling, the local Python interpreter that is used to run
ensurepip may not have the same value of sys.prefix as the value of the
'prefix' variable that is set in the Makefile.
With the following values used to install Python locally for a later copy to
the files hierarchy owned by the 'termux' application on an Android device:
DESTDIR=/tmp/android
prefix=/data/data/com.termux/files/usr/local
'make install' causes ensurepip to install pip in $(DESTDIR)/usr/local instead
of the expected $(DESTDIR)/$(prefix) where is installed the standard library.
The attached patch fixes the problem. The patch was implemented assuming that
pip uses distutils for the installation (note that setup.py also uses the
--prefix option in the Makefile), but I know nothing about pip so forgive me if
the patch is wrong and please just assume it is just a way to demonstrate the
problem.
