MULTILIB_EXTRA_OPTS and LIBGCC2_CFLAGS

[Paulo J. Matos]

Hi all,

I am quite confused about the difference between the above two options 
in Makefile fragments.

They both seem to be doing the same thing which is to set the options to 
build libgcc2 with.

The only thing that comes to mind is that LIBGCC2_CFLAGS only applies to 
the main library and MULTILIB_EXTRA_OPTS applies to all the 'specially' 
build libgcc2 that go into MULTILIB_DIRNAMES.

Anyone can confirm this?

Cheers,
