Dear Maintainer,


armhf build is failing with clang21.

2 changes are needed to fix the build failure:

  * d/rules: drop -fno-stack-clash-protection from C/C++ flags.
    clang does not implement stack-clash protection on armhf, so this flag
    is an unused argument. meson promotes the resulting warning to an error
    during its compiler checks (-Werror=unused-command-line-argument),
    which made the pthread.h check fail and broke configure on armhf.

 * d/p/fix-cache-size-narrowing-32bit.patch

Thanks for considering the patch.
