Add a __section(x) macro as well. Use this in linker_set.h. ie:

Browse Source 
static void const * const __set_##set##_sym_##sym
 __attribute__((__section__("set_" #set),__unused__)) = &sym
becomes:
static void const * const __set_##set##_sym_##sym
 __section("set_" #set) __unused = &sym
Like the other macros, these #define away for unrecognized compilers or
lint.

Also, fix the argments in the previous commit for the non-gcc case. lint
might be a bit happier about that.  Note that the gcc <= 2.6 case
needs some research.
