llvm-runtimes/libgcc: New package, 19.1.7 and 20.x llvm-libgcc[0] is the LLVM subproject which provides a link script, which can be used to build a library linked to compiler-rt and llvm-libunwind, which serves as a full replacement of libgcc_s. The main purpose of having it in Gentoo is ability to run binaries, linked to libgcc_s, on musl-llvm systems.
