compiler-gcc.h: __nostackprotector needs gcc-4.4 and up
commit d9afaaa4ff7af8b87d4a205e48cb8a6f666d7f01 upstream.
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")
