[oe] [PATCH 1/2] u-boot-sakoman: fix break caused by the new binutils

[Khem Raj]

2011/1/24 Víctor Manuel Jáquez Leal <vjaquez at igalia.com>:
> New assemblers need -march=armv7-a+sec on command line or .arch_extension sec
> inline to enable use of the smc instruction.
>
> This patch adds as-instr to check the latter to conditionally enable the
> former in AFLAGS for files that use smc.
