[Ecls-list] More on builtins

[Juan Jose Garcia-Ripoll]

I have been reviewing old manuals of GCC. The first reference to "noreturn"
and "longjmp" together is found in v4.0. I have thus decided to go the
daring route and define a new macro, ecl_attr_noreturn as
__attribute__((noreturn)) for all versions >= 4.0  The result is a
tremendous size reduction in the core, of about 17k! Not bad for starters.

$ size build.attr/libecl.dylib
__TEXT __DATA __OBJC others dec hex
1318912 253952 0 532480 2105344 202000
$ size build/libecl.dylib
__TEXT __DATA __OBJC others dec hex
1335296 253952 0 532480 2121728 206000
