Hello team,

What is the way to disable `-mss2 for aarch64 build in embree?

Spec file:
https://src.fedoraproject.org/rpms/embree/blob/rawhide/f/embree.spec

Scratch build result:
https://koji.fedoraproject.org/koji/taskinfo?taskID=88867571

Are you sure your scratch build corresponds to the linked spec file?

The spec file reads:

    %ifarch x86_64
            -DEMBREE_MAX_ISA=SSE4.2 \
    %else
            -DEMBREE_MAX_ISA=NONE \
    %endif

but the build.log shows:

    + /usr/bin/cmake -DCMAKE_C_FLAGS_RELEASE:STRING=-DNDEBUG -DCMAKE_CXX_FLAGS_RELEASE:STRING=-DNDEBUG -DCMAKE_Fortran_FLAGS_RELEASE:STRING=-DNDEBUG -DCMAKE_VERBOSE_MAKEFILE:BOOL=ON -DCMAKE_INSTALL_DO_STRIP:BOOL=OFF -DCMAKE_INSTALL_PREFIX:PATH=/usr -DINCLUDE_INSTALL_DIR:PATH=/usr/include -DLIB_INSTALL_DIR:PATH=/usr/lib64 -DSYSCONF_INSTALL_DIR:PATH=/etc -DSHARE_INSTALL_PREFIX:PATH=/usr/share -DLIB_SUFFIX=64 -DBUILD_SHARED_LIBS:BOOL=ON -DCMAKE_BUILD_TYPE=Release -DCMAKE_CXX_STANDARD=17 -DCMAKE_INSTALL_LIBDIR=/usr/lib64 -DCMAKE_INSTALL_PREFIX=/usr -DEMBREE_COMPACT_POLYS=ON -DEMBREE_IGNORE_CMAKE_CXX_FLAGS=OFF -DEMBREE_ISPC_SUPPORT=ON -DEMBREE_MAX_ISA=DEFAULT -DEMBREE_TUTORIALS=OFF

There is -DEMBREE_MAX_ISA=DEFAULT instead of -DEMBREE_MAX_ISA=NONE.

Morover, I'm not sure whether upstream supports a generic AArch64. README.md
reads:

    Embree requires at least an x86 CPU with support for
    SSE2 or an Apple M1 CPU.
