Subject: [PATCH 1/5] alpha: remove a.out support from tools/objstrip
Date: Thu, 23 Nov 2023 18:02:41 +0000 [thread overview]
Message-ID: <20231123180246.750674-2-dimitri.ledkov@canonical.com> (raw)
In-Reply-To: <20231123180246.750674-1-dimitri.ledkov@canonical.com>
As a.out support has been dropped from alpha port, drop a.out support
and make ELF support required.
Only performed a test build on x86 for native x86 and cross-compiled
for alpha.
