I received an answer from Raúl Porcel via gentoo-embedded mailing list: AFAIK gnueabi is only for ppc and ARM. Also softfloat(specifying it on the CHOST on gentoo) is for arm only. http://gcc.gnu.org/onlinedocs/gcc-4.4.0/gcc/SPARC-Options.html#SPARC-Options You'll need to use -mno-fpu on the CFLAGS. And again, the -softfloat- thing on the CHOST is gentoo-specific and only applies to ARM. So i'm closing a bug.
