(In reply to Piotr Kubaj from comment #4)

Sounds reasonable. Could we:

- Wrap this in an LTO option, enabled by default, excluded on architectures=
 its
not relevent or ok for.

- Update the patch to include changes for all lang/python* ports that suppo=
rt
it (LTO). I think more than one does.

- Can we get away without the 'CC=3D environment override', leaving in eith=
er:

1) the current check for =3D=3D cc, or=20
2) using appropriate ports framework mechanisms to determine whether the
compiler is clang? ie:

if excluding options based on arch is feasible:

   if option and correct-compiler=20

If not:

   if option and correct compiler and not bad-arch

Note that while pythons configure checks CC, it also incorrectly detects 'G=
NU
linker' (based on version string), and the build system is not very robust =
with
respect to toolchains, and if we can just do the 'is this the right toolcha=
in
for lto' parts in ports, that would be preferable.

--=20
