[PATCH v1 0/8] Add loongarch64 architecture support to IPFire

[Vincent Li <vincent.mc.li@gmail.com>]

This patch series adds initial support for the LoongArch64 architecture
to the IPFire build system and installer. LoongArch64 is the 64-bit
RISC architecture developed by Loongson Technology, using UEFI as its
standard firmware interface.

The series includes:

1. **Build system detection** (make.sh): Add architecture detection
   for loongarch64 in the main build script.

2. **Toolchain fixes** (gcc): Fix dynamic linker path for native
   bootstrap to ensure glibc builds correctly.

3. **Package build system** (lfs/Config): Update config.guess/sub
   scripts to recognize loongarch64 as a valid architecture.

4. **EFI and GRUB support** (lfs/Config): Define architecture
   variables for building EFI firmware and GRUB for loongarch64.

5. **Go language support** (lfs/Config): Set GOARCH=loong64 for
   building Go packages.

6. **Installer EFI detection** (installer): Enable EFI boot mode
   detection for loongarch64 systems.

7. **Installer bootloader** (installer): Add GRUB installation
   support for loongarch64-efi.

8. **Kernel build** (kernel): Add architecture definitions and
   special handling for building the Linux kernel on loongarch64.

These changes are the foundation for a complete loongarch64 port
of IPFire and have been tested on a LoongArch64 development system.
