Confirmed with GCC 4.8.3.

is this only on i686?  also does it work with gcc 4.7?
Comment 5 Mike Gilbert gentoo-dev 2014-10-21 20:13:30 UTC 
The -fuse-ld option was added in gcc-4.8. It generates an error with gcc-4.7.
Comment 6 Mike Gilbert gentoo-dev 2014-10-21 20:16:16 UTC 
Also, have a look at sys-boot/grub:2 for a more compatible solution. Snippets below.

Apologies -- next time I try and fix a system package I will do a lot more testing (including more than one toolchain version) before committing.

Comment 8 SpanKY gentoo-dev 2014-10-22 20:47:19 UTC 
you shouldn't test gcc versions.  this is why we have test-flags-CC.
