Ah, so that's something different, not CFLAGS.

Not true here.  It works just fine for me.  Did you really try with my
patch applied?

It doesn't.  The Linux kernel intentionally does not make use of
libgcc.a but supplies it's own code.  U-Boot does the same when you
build with CONFIG_USE_PRIVATE_LIBGCC=y; there hav ebeen too many
compiler versions around with incompatible/incomplete/incorrect
versions of libgcc, so we try to not depend on these in low-level
projects like the kernel or U-Boot.

Best regards,

Wolfgang Denk
