Marc-Andre Lemburg added the comment:
Reading the ticket, it seems that there is some confusion about what LDSHARED
and BLDSHARED are used for. BLDSHARED is used to override the LDSHARED value
when building libpython and the shared modules (via setup.py).
LDSHARED is what is meant to be used for building shared modules after
installation.
This distinction is not being followed by all targets in the Makefile, but is
needed in cases where special build tools are necessary, as is the case on AIX.
For the latter, BLDSHARED has to point to the source tree version of those
build tools, while LDSHARED has to point to the installed version of these.
On AIX, BLDSHARED should therefore point to the ./Modules/ld_so_aix (or better:
the absolute dir of the source tree), while LDSHARED needs to point to the
installation target for ld_so_aix, e.g.
/usr/local/lib/python2.7/config/ld_so_aix.
So the fix which was already applied to 3.4 is correct for 2.7 as well. The
missing part is the fix to the configure script, since in Python 2.7, this
still uses relative paths:
BLDSHARED="Modules/ld_so_aix \$(CC) -bI:Modules/python.exp"
LDSHARED="\$(BINLIBDEST)/config/ld_so_aix \$(CC)
-bI:\$(BINLIBDEST)/config/python.exp"
instead of the ones from 3.4:
BLDSHARED="\$(srcdir)/Modules/ld_so_aix \$(CC)
-bI:\$(srcdir)/Modules/python.exp"
LDSHARED="\$(BINLIBDEST)/config/ld_so_aix \$(CC)
-bI:\$(BINLIBDEST)/config/python.exp"
