- 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.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
