search path for compiler components

3.14 Options for Directory Search
-Bprefix
It tries prefix as a prefix for each program it tries to run, both
with and without ‘machine /version /’
--------------------------------
I am using gcc, version 4.4.4 of Fedora 12.
The compiler path is as follows:
COMPILER_PATH=

/usr/libexec/gcc/i686-redhat-linux/4.4.4/
/usr/libexec/gcc/i686-redhat-linux/4.4.4/
/usr/libexec/gcc/i686-redhat-linux/4.4.4/
/usr/libexec/gcc/i686-redhat-linux/
/usr/libexec/gcc/i686-redhat-linux/
/usr/lib/gcc/i686-redhat-linux/4.4.4/
/usr/lib/gcc/i686-redhat-linux/4.4.4/
/usr/lib/gcc/i686-redhat-linux/
/usr/lib/gcc/i686-redhat-linux/

I just reordered the result by gcc -v and then put each path on a
separate line. Why "machine /version /"  rule of the gcc manual is not
kept here?
