Compiling the GCC package is very difficult for any computer. Especially for a hard drive. Often, the updating of the compiler is carried out by some users before the rest of the system is updated.

As a result, the Portage system requires a subsequent re-assembly of the compiler. This is a completely impractical solution to compile the compiler twice in this situation. Reproducible: Always
