Backport chaqnges from el10 branch

  • Improved gcc spec ( splitted in to gcc-prerequisites)
  • Bukld GCC with --enable-frame-pointer which by default enables frame-pointers for all packages built with this GCC on X86_64. Note that this does not enable frame-pointers for aarch64
  • updated cmake to version 3.31. which has a fix for newer curl
  • sync curl changes from el10 branch to reduce the differences between el10 and g14 branch
