Subject: [PATCH] compiler-gcc.h: __nostackprotector needs gcc-4.4 and up
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Gcc versions before 4.4 do not recognize the __optimize__ compiler
attribute:

    warning: ‘__optimize__’ attribute directive ignored

Fixes: 7375ae3a0b79ea07 ("compiler-gcc.h: Introduce __nostackprotector function attribute")
