Build log of dev-libs/libedit

Hi. I'm getting error on a system with musl while buildihg dev-libs/libedit:

> error: wchar_t must store ISO 10646 characters        #error wchar_t must store ISO 10646 characters

Some little googling is giving me this solution:

> Musl is ISO 10646 compliant but doesn't define __STDC_ISO_10646__, so
let's define it manually.

(link removed by new account restrictions of bugzilla)

So i made this workaround for the ebuild:

--- /var/db/repos/gentoo/dev-libs/libedit/libedit-20221030.3.1.ebuild.orig	2023-04-20 06:31:59.533722158 +0000

And package builds fine for me with this patch.
