Subject: [Buildroot] [PATCH 1/1] package/make: fix build with musl and gcc-15.x
Date: Sun,  3 May 2026 19:56:37 -0400	[thread overview]
Message-ID: <20260503235637.637991-1-Software@DRHouck.me> (raw)

It builds fine with glibc and gcc-15.x but conditionally includes code
with musl that fails.  See eg. commit 999fb19d4b.

Fixes #176.  See also https://savannah.gnu.org/bugs/index.php?68302
