scipy: update to v1.15.2

[T-Dynamos]

Closes #3116

Cons:

1. Can't build on macos
2. Needs android 7 and 7+
3. Only 64 bit arches supported

Extra Notes:

Removes need to use LEGACY_NDK as it uses fortran from https://github.com/termux/ndk-toolchain-clang-with-flang.

SDL does not builds with ndk r27c because of libsdl-org/SDL#9792.
So we need to wait for #3125.

Will continue working on the SDL3 recipes this weekend, however we are going to support both SDL2 and SDL3 for a long time, as only Kivy 3.0.0 will support SDL3, and will not be ready quite soon.

Maybe we can use NDK 27 only for some specific recipes? (or a previous one for SDL2)

[T-Dynamos]

Just saw fixed was also pushed for SDL2, so bumped version to include that fix. :)

Impressive work so far!
Thanks for picking this up too @T-Dynamos 🙏
Maybe it's a good time to rebase it since SDL3 (#3125) was merged

Should I document this things or add warnings in code:

 Can't build on macos
 Only 64 bit arches supported

Yeah maybe failing early with an explicit message would do it, what do you think?
Which makes me think, maybe in the future we want a consistent behavior for this case and have something like "unsupported_arch" attribute in a recipe (empty by default) that would make the build fail fast with an explicit message.
