This Bug is well known, trivial to fix[1], and has even been reported before[2] but for some reason in Gentoo Prefix it still isn't fixed. [1] http://trac.cross-lfs.org/ticket/926 [2] http://www.mail-archive.com/gentoo-alt@lists.gentoo.org/msg06751.html
Thanks, applied the workaround
For the records: binutils-2.24 ships with this fixed: Dropped workaround as it creates '@@@colophon', breaking again.
