Regression on Darwin: `Undefined symbols for architecture ppc: ___stdlib_string_type_MOD_new_string`

[barracuda156]

Description

Current master fails to build on powerpc-apple-darwin with a linking error:

Undefined symbols for architecture ppc:
  "___stdlib_string_type_MOD_new_string", referenced from:
      ___stdlib_io_MOD_get_line_string in stdlib_io.f90.o
ld: symbol(s) not found for architecture ppc

Expected Behaviour

The build should succeed, like it was earlier.

Version of stdlib

d57c776

Platform and Architecture

macOS 10.6.8 / ppc

Sorry to hear that @barracuda156 . Can you provide the command lines you run please?

[barracuda156]

@jvdp1 Thank you for responding. There was no change to how we build this: https://github.com/macos-powerpc/powerpc-ports/blob/567af6afb557a50c5df71a5548961754b03737b4/lang/fortran-stdlib/Portfile#L62-L74

The last commit known to have built is 60f5308
(Bisecting is doable but mildly painful, I do not have the fast G5 at hand now, it can take a lot of time if done blindly.)

@jalvesz @perazz Any idea what could be the issue?

[perazz]

The "modularized" CMake lapack library includes stdlib_io.fypp which uses the string_type
constructor. This constructor is implemented in the submodule stdlib_string_type_constructor, which in turn depends on stdlib_strings and its submodule stdlib_strings_to_string.

I have tried a quick fix but things seem more complicated than that, and I don't have much experience with cmake
