-# 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.
