python27 @2.7.5 has bad LINKFORSHARED sysconfig

[wichert@…]

After doing a port upgrade and getting the latest python27 port autoconf is now breaking on python tests. This is caused by autoconf picking up the linker options from python itself:

>>> import distutils.sysconfig
>>> distutils.sysconfig.get_config_var('LINKFORSHARED')
'-u _PyMac_Error Python.framework/Versions/2.7/Python'

Which shows an incomplete path is used, which causes the autoconf test to fail like this:

clang -o conftest -g  -I/opt/local/Library/Frameworks/Python.framework/Versions/2.7/include/python2.7  conftest.c  -L/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/config -lpython2.7 -u _PyMac_Error Python.framework/Versions/2.7/Python  -ldl  -framework CoreFoundation
clang: error: no such file or directory: 'Python.framework/Versions/2.7/Python'

This appears to be due to a change in python itself: in python 2.7.3 distutils.sysconfig._init_posix use to parse /python2.7/config/Makefile, but that was changed to read lib/python2.7/_sysconfigdata.py instead. This suggest a workaround is to do the same replace trick for that file as well.

Thanks for the ticket. In the future, please Cc relevant port maintainers.

Looks like #39337 was caused by this.

Guess this is a duplicate of that.
