- Add new build dependencies to lld and llvm
- Add host-gcc and gcc >= 7.x dependency since clang doesn't build with gcc 6.3

Indeed LLVM_TEMPORARILY_ALLOW_OLD_TOOLCHAIN is OFF, the CheckCompilerVersion.cmake
trigger an error if gcc < 7.x. Indded since llvm 15 this option check for C++17 [1]
The last gcc 7.x version (7.5) has been released in 2019.
Fixing llvm/clang issues for old compiler maybe it's not worth it.
- Remove LLVM_TEMPORARILY_ALLOW_OLD_TOOLCHAIN since
gcc >= 7 is mendatory.
When updating LLVM, we also need to update the version of
SPIRV_LLVM_TRANSLATOR because its CMakeLists.txt verifies the LLVM
base version [2].
The patch
package/llvm/0002-Add-missing-cstdint-header-to-Signals.h.patch has
been included in tag llvmorg-15.0.0 of llvm-project.
