/usr/lib/gcc/x86_64-alpine-linux-musl: libgettextlib.so: undefined reference to `libiconv'

[Jeffrey Walton]

Hi Everyone,

I'm building libiconv 1.16 and gettext 0.20.2 on Alpine Liniux 3.10.
Alpine's claim to fame is Musl instead of glibc.

GetText is configured to use libiconv shared object using
--with-libiconv-prefix="$MY_PREFIX". (MY_PREFIX is valid).

The build results in the following. I believe the make recipe is
lacking $(LTLIBICONV) library, and it is causing the link problem.
