Why you want gcc-3.4.6 to be used with the CentOS 7 native C libraries ? (Some quite new glibc there)  The produced native toolchain would produce executables which as default would only work on CentOS 7 and newer than that releases. Not on CentOS 6, 5, 4, 3, 2, 1, on old Fedora releases or RedHat releases... One sane goal would be to get a toolchain on CentOS 7 which produces executables for some older CentOS (or something else) release which had gcc-3.4.6 as its original native GCC or as a self-made updated native GCC. That using some old glibc as its native C library.  This goal meaning producing a crosstoolchain to the old Linux release (building binutils and GCC to use the old glibc as prebuilt in a $sysroot)
