[Buildroot] [PATCH] at91bootstrap: fix gcc-4.6.x overlap linker issue

[Thomas Petazzoni <thomas.petazzoni@free-electrons.com>]

Dear Gr?gory Hermant,

Your patch is line-wrapped, so it won't apply. Can you resend it with
'git send-email' instead, or at least make sure your MUA is properly
configured not to wrap lines (but using 'git send-email' is a much
easier and reliable solution IMO).

Thomas
