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.

# differences:
|

#
|

# * We build the local copy of compiler-rt manually, to have a full control
|

# over CMake options.
|

# * Upstream links the locally built copy of libunwind statically. We link the
|
||||
# system-wide libunwind dynamically.
