gentoo-overlay/dev-cpp/folly/files/folly-2022.07.04.00-musl-fix.patch

# Elf.cpp expects __ELF_NATIVE_CLASS to be defined at least for platforms
# besides FreeBSD-based ones, and so it defines FOLLY_ELF_NATIVE_CLASS with it.
# Without __ELF_NATIVE_CLASS (and apparently musl does not define it),
# FOLLY_ELF_NATIVE_CLASS is also not defined so what was supposed to be
# expanded to ELFCLASS32 or ELFCLASS64 ends up being
# ELFCLASSFOLLY_ELF_NATIVE_CLASS.
#
# Please refer: https://github.com/facebook/folly/issues/1478
#
# Closes: https://bugs.gentoo.org/835744
