Summary: Build error using make VPATH feature

Initial Comment:
PROBLEM DESCRIPTION
=====================

After building successfully Python 2.2.2 from scratch
on Solaris 8 using the usual commands (cd
~wrk/Python-2.2.2; ./configure; make), I decided to
build it for multiple architectures (SunOS 5.6, 5.7 and
5.8), exploiting the supported VPATH feature of GNU make.

Here are the commands I run for Solaris 6:

1. mkdir ~/wrk/Python-2.2.2/binaries/SunOS_5.6
2. cd ~/wrk/Python-2.2.2/binaries/SunOS_5.6
3. ../../configure -prefix=/usr/local/python
4. make

Unfortunately the last command failed with the
following error:...
ranlib libpython2.2.a
gcc  -Xlinker --export-dynamic -o python \
		Modules/python.o \
		libpython2.2.a -lsocket -lnsl -ldl  -lpthread -lthread  
-lm

such file or directory)
make: *** [sharedmods] Error 1

PROBLEM ANALYSIS==================
By looking the code inside sysconfig.py module, it is
clear that the problem is generated by the first IF
clause (starting at line 32), where the python_build
variable is set: the path obtained by joining "Lib" to
the argv0_path variable does not exist, since no
directory named Lib exists in the (current) work
directory. In fact the only existing directories  are:
 - Grammar
 - Modules
 - Objects
 - Parser
 - Python
 - build


WORKAROUND
=============
Simply create a link to the Lib directory provided with
Python 2.2.2, i.e. in my example:

ln -s ../../Lib
make
make test
make install
