Order of Rebuilding Complete Toolchain in Linux

First update Linux header files and toolchain components once in following order: linux-header glibc binutils gcc

Now upgrade is made, but still the machine codes are from legacy toolchains. So we’re urged to renew the machine code of toolchain components themselves.

One note: in Gentoo Linux, you have to run gcc-config to check whether the new version is selected as the default compiler, or your Gentoo box will still use the legacy version to compile everything.

The order is as follows - glibc binutils gcc.

The reason to build glibc first? That’s because it affects to the content of binutils and gcc. :P
