This patch modifies the build system to analyze the version of the target ARM architecture and setup the compiler flags accordingly. This makes it possible to support the ARM architectures prior to ARMv7. Signed-off-by: Alexander Kartashov <alekskartashov@parallels.com> Signed-off-by: Pavel Emelyanov <xemul@parallels.com>
