# If say both gcc and binutils were built for i486, and we then merge
# binutils for i686 without removing the i486 version (Note that this is
# _only_ when its exactly the same version of binutils ... if we have say
# 2.14.90.0.6 build for i486, and bootstrap then merge 2.14.90.0.7 for i686,
# we will not have issues.  More below ...), gcc's search path will
# still have
#
#   /usr/lib/gcc-lib/i486-pc-linux-gnu/<gcc_version>/../../../../i486-pc-linux-gnu/bin/
#
# before /usr/bin, and thus it will use the i486 versions of binutils binaries
# which causes issues.  The reason for this issues is that when bootstrap merge
# exactly the same version for i686, both will have installed the same files to
# /usr/lib, and thus also USE the same libraries, cause as/ld to fail with
# unresolved symbols during compiling/linking.
#
# More info on this can be found by looking at bug #32140:
#
#   http://bugs.gentoo.org/show_bug.cgi?id=32140
#
# We now thus run an 'emerge clean' just after merging binutils ...
