Subject: [PATCH 7/7] ARM: remove EABI/OABI selection
Date: Sun,  9 Jan 2011 01:45:10 +0100
Message-Id: <1294533910-19305-8-git-send-email-yann.morin.1998@anciens.enib.fr>
X-Mailer: git-send-email 1.7.1
In-Reply-To: <1294533910-19305-1-git-send-email-yann.morin.1998@anciens.enib.fr>
References: <1294533910-19305-1-git-send-email-yann.morin.1998@anciens.enib.fr>

Rely on the compiler to be properly setup for the default ABI.

When installing-headers, there are two cases:
- NPTL: no issue, a cross-compiler is already expected
- LinuxThreads: no issue, EABI/OABI has no impact on installed headers.
