[PATCH] tools/python: Pass linker to Python build process



Unexpectedly the environment variable which needs to be passed is
$LDSHARED and not $LD.  Otherwise Python may find the build `ld` instead
of the host `ld`.

Replace $(LDFLAGS) with $(SHLIB_LDFLAGS) as Python needs shared objects
it can load at runtime, not executables.

This uses $(CC) instead of $(LD) since Python distutils appends $CFLAGS
to $LDFLAGS which breaks many linkers.
