gentoo-overlay/dev-util/debugedit/files/debugedit-5.0-musl-error.h-fix.patch

# musl doesn't provide error.h as a result debugedit is failing to build on
# musl.
#
# With advice from developer Anthony G. Basile <blueness@gentoo.org> I went
# with creating a define that redefines the err function. The major
# improvements over the previous implementation is that this time the patch is
# smaller and more readable compared to previous implementation.
#
# Closes: https://bugs.gentoo.org/714206
