Add support for building loong64

README.md

@@ -17,6 +17,7 @@ This list of officially supported platforms is available in the Node.js [BUILDIN
  * **linux-x86**: Linux x86 (32-bit) binaries compiled against libc 2.17, similar to the way the official [linux-x64 binaries are produced](https://github.com/nodejs/node/blob/master/BUILDING.md#official-binary-platforms-and-toolchains). 32-bit Linux binaries were dropped for Node.js 10 and 32-bit support is now considered "Experimental".
  * **linux-armv6l**: Linux ARMv6 binaries, cross-compiled on Ubuntu 16.04 with a [custom GCC 6 toolchain](https://github.com/rvagg/rpi-newer-crosstools) (for Node.js versions earlier than 16) or Ubuntu 18.04 with a [custom GCC 8 toolchain](https://github.com/rvagg/rpi-newer-crosstools) (for Node.js 16 and later) in a similar manner to the official linux-armv7l binaries. Binaries are optimized for `armv6zk` which is suitable for Raspberry Pi devices (1, 1+ and Zero in particular). ARMv6 binaries were dropped from Node.js 12 and ARMv6 support is now considered "Experimental".
  * **riscv64**: Linux riscv64 (RISC-V), cross compiled on Ubuntu 20.04 with the toolchain which the Adoptium project uses (for  now...). Built with --openssl-no-asm (Should be with --with-intl=none but that gets overriden)
+ * **loong64**: Linux loong64 (LoongArch64), cross compiled on Ubuntu 20.04 with the toolchain.
 
 "Experimental" status for Node.js is defined as:
 > Experimental: May not compile or test suite may not pass. The core team does not create releases for these platforms. Test failures on experimental platforms do not block releases. Contributions to improve support for these platforms are welcome.
