libgfortran, libgomp not compiled with BOOT_CFLAGS.

[Toon Moene]

L.S.,

Recently, I've begun to bootstrap with make BOOT_CFLAGS="flags", 
basically to get the run time libraries (libgfortran, libgomp) compiled 
with -mcpu=native -mtune=native (the speed of the compiler doesn't 
interest me that much).

However, I see that almost everything is compiled with -mcpu=native 
-mtune=native, *except* the run time libraries ...

Is that because they're target libraries - if so, how would one get them 
compiled "optimally" if not building a cross-compiler ?

Thanks in advance for any insight.
